Note: Answers will occasionally be moved to the Sandbox archive when there are too many of them. When using them to report bugs, keep an eye.

As per Jeff's suggestion in this comment:

You can use this question as a formatting sandbox. You can:

  • edit this question itself (Community Wiki questions such as this one require 100 reputation to edit)
  • post answers to this question (This question might be protected, requiring earning 10 reputation on this site to answer)
  • post comments to this question or its answers
  • test suspected bugs with the editor or the rendering
  • post ponies (only when mods are asleep)

Beware that since the changes to syntax highlighting in December 2010, and the inline hints added in March 2011, no syntax highlighting is applied unless the question's tags or an inline hint enable it. So, to test highlighting here in the sandbox:

  1. As of January 8, 2019, you can use GitHub-flavor fenced code blocks in your posts, specifying the language after the opening fence:

    While not hinted otherwise: <html></html> source <b>goes</b> "here".
    var a = 3;
    while (not (a > 0)) {
        alert("JavaScript code <b>goes</b> here.");
  2. (The traditional way) On the start of a line, specify a language inline using <!-- language: lang --> hints, and indent the code 4 spaces as usual. There is a full list of hints (scroll down a little).

    <!-- language: lang-html -->
        While not hinted otherwise: <html></html> source <b>goes</b> "here".
    <!-- language: lang-js -->
        var a = 3;
        while (not (a > 0)) {
            alert("JavaScript code <b>goes</b> here.");
  3. Or:

    • Create code blocks in either way (see above).

    • Save your post.

    • Use your browser's developer tools to edit the resulting HTML. To open developer tools, press F12, or ⌥⌘ I on Mac.

    • Find the <pre> element and add the attribute class="prettyprint", or change it into one of the valid syntax hints linked above, like class="lang-vb prettyprint".

    • Run the following in the location bar: javascript:prettyPrint(); or prettyPrint() in the console.

Answers that are considered annoying or obnoxious, or that cause breakage for users, will be deleted. This is codified as a policy as of March 29, 2018.

    A comment with some weird markdown, to test and help this user. Look tags work too, and so does tour. – Bhargav Rao Apr 6 at 1:59
  • Note: Do not remove @BhargavRao's comment, or you will break this answer – wizzwizz4 Apr 6 at 17:16
  • @BhargavRao When sandbox answers are moved to the archive, comments such as this one -- on the question itself -- aren't migrated; they're deleted. – rgettman Apr 9 at 19:37
  • @rgettman, yeah, that is fine. I had used it for just a small demonstration. The linked answer itself is self-sufficient. Thanks anyway. – Bhargav Rao Apr 9 at 20:22
  • @BringBackThePolyglot Do you get notifications if I reply to your comment and then delete your comment before you visit the site? (for those wondering how I can single-handedly delete someone else's comment, comments containing "thanks" are automatically deleted as soon as someone flags them) – Donald Duck Apr 25 at 16:32
  • @DonaldDuck Yes, I got notified. – Bring Back The Polyglot Apr 25 at 16:32
  • honestly the over 500 hundred upvotes for a sandbox post is taking this real time satire thing you guess do with rep points too far – Adam May 7 at 11:14
  • It makes me feel like doing one too like an onion announcing the Debian contributor community have been assigned complete authority and trust over all encryption matters for the central banks of the world but no, im an adult, I can show restrain – Adam May 7 at 11:16
  • thanks thanks thanks – Adam May 7 at 11:17
  • no I'm seriously asking now, what does op mean when someone causes a user "breakage"? is that like the time I was not allowed to take the archer profile pic down for like 6 months? that did break me tbh – Adam May 7 at 11:22

    This is a sandbox post, it doesn't need to make sense. Really, there's absolutely nothing to see here :) – Glorfindel Jun 5 at 5:09
  • hmm.... adding one word gave me 4% contribution. Interesting. Would love to see the source code calculating that percentage... – ShaWiz Jul 17 at 8:50
  • I'm sorry if I mess up your testing - I was doing another test right now. – Glorfindel Jul 17 at 8:56
  • All good! Now I'm down to 3% lol. If I may ask, what are you testing? ;) – ShaWiz Jul 17 at 8:58

  • Yeah, that too :) – Glorfindel Jul 17 at 9:10

just a test

  • @MikeM. please don't hijack random post, even in sandbox. It cause inbox message to be sent, which some people consider as noise. Post your own answer and test comments as much as you want under that answer. Thanks. – ShaWiz Apr 11 at 14:17

    @ShadowWizard That's totally my bad. I didn't think anybody got pinged on community wiki. I meant to immediately delete that anyway. My apologies. – Mike M. Apr 11 at 14:19

These answer Arqade's 2019 questionnaire

  1. You (a moderator) and another community member both answer a question (not on Meta). The other answer is well written but (objectively) incorrect, and has gathered a similar amount of upvotes to yours. What do you do?

I would downvote the other user's answer. I am quite opposed to keeping really bad answers that are objectively incorrect, and would downvote due to my view.

  1. A relatively new community member has shown misgivings about an established site policy and has a suggestion to change the policy. Their suggested change (posted on meta) isn't being well received by community regulars and the debate appears to be drifting in an unfriendly direction.
    How do you approach and respond to this situation?

I would go to the Meta and, in the comments, warn the users that this seems to be going in a bad direction. If it kept going and got very bad, I would delete the comments and leave one mentioning the deleted comments and also saying to be nice, linking to our policy.

  1. The Restaurant at the End of the Universe, our main chat room, is one of the most active on the network. Do you see the moderation of Sci-Fi's chat rooms as part of your duties? If you're not active in chat currently, would you consider it part of the job to keep an eye on what's going on there?

I am always on The Restaurant at the End of the Universe, but it is always pretty nice over there. If something went wrong, I would actively try to defuse the situation.

  1. Moderators are not selected because they are domain experts in certain tags, but it so happens that you are an expert in one such tag. You see that several members of the community have elected to close a question as a duplicate, but you see that the duplicates don't actually answer the question as stated, nor do they provide a useful signpost for the asker. How do you proceed?

I would comment as such, pinging the close voters and maybe making a Meta post. If it were extremely clearly not a duplicate, I would re-open.

  1. There is a high-rep user who is very active on the site, but frequently uses strong language which violates the Code of Conduct in their comments. When you warned them, they replied stating that the questions are of low quality which is why they left those comments. They also threatened to quit the site. Despite the warning, they continue to post similar comments. What steps, if any, will you take in order to address this situation? What if the comments were on Meta instead of main? Does that change your approach at all?

This is a hard question. If they were extremely frequent and very bad (like using the n-word), I would discuss a suspension in the mods' chatroom. If they weren't so horrible, I would give them warnings. If they were on Meta, I would act exactly the same.

  1. We have a very active chat community, but at the end of the day, it is a very small part of our actual community. Sometimes, people discuss site policy in chat as if ruling decisions can be made there, instead of moving them to meta. How would you deal with this? How much value do you place on chat as a place of community consensus?

I think that stuff such as minor re-tagging or deletion of bad tags with few questions on them is not so significant that we should freak out if it happens on chat. However, big stuff, e.g. something like removing the [cosmere] tag from all questions concerning only one work1 should definitely not be decided on chat; that should be discussed on our meta.

  1. How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?

This would have to be discussed with the other mods who have more experience moderating than me. I would watch all this user's comments to see if there's anything that should be deleted or that they should be punished (maybe with a short suspension) for.

  1. How would you handle a situation where another mod closed/deleted/etc a question that you feel shouldn't have been?
    How do you react, in particular, if nobody has communicated with the moderator regarding this action, or disagreed with it through voting, posting on meta, or any other means?

I would post a meta on it. Due to my vote being unilateral, I'd have a discussion with the community before taking any actions.

  1. A diamond will be attached to everything you say and have said in the past, including questions, answers and comments. Everything you will do will be seen under a different light. How do you feel about that?

Except for my silly questions on chat, I think I am a (relatively) competent and unrude-seeming person so I wouldn't really have anything to change.

  1. As a moderator, would you use your binding vote to unilaterally approve and reject suggested edits, or would you leave these to the community review vote?

I think that suggested edits are awesome (I actually have hit the 500-edit reputation cap for them) and important to review, so I would use my vote to get the good ones approved and the users rewarded and the stupid, useless ones rejected.
