How to contact moderators
- Contact them in a chat room. Many moderators are active in one or more chat rooms, and pinging them (with a simple @[whatever-their-name-is]) can notify them, and then you can discuss whatever you want to discuss. A user must have posted a message in the chatroom in the past week for a normal user to be able to ping them. Also, I noticed your main site is Super User, so this might help you.
- Email link in profile. Some people put an email link in their profile, to make themselves available for contact. However, some people might not want to be contacted for in-site matters.
- Bring it up on the per-site meta. For some things that you think are very important (e.g. a deleted your answer which you think was a good answer) you can bring it up on the per-site meta of your site. The per-site meta can be found by clicking the SE logo in the top right, which should open a menu with the option to take you to the per-site meta. Note: this site (meta SE) does not have a per site meta.
- Flag a post for moderator attention. I would highly recommend against doing this in most situations, but it is an option.
Response to your first example
Editing the post should have placed it into the re-open queue, so maybe it hasn’t been reviewed yet (as the queue has a massive backlog on some sites), or maybe your question still has problems. I would recommend bringing it up in chat, or maybe the per-site meta if chat doesn’t work.
Response to your second example
As mentioned in the comments, that suggested edit was approved by community members, not a moderator. If you don’t like the edit, you can roll it back, and you can leave a comment saying something like “hi @[editors-username], I rolled back your edit because of [reason], if you think it was a good edit I would be happy to discuss it in the comments”.
Answer to specific questions
- No.
- See above.
- Chat is a real time messaging system, and yes, only some users use chat, not all of them. Looking at some posts on your sites per-site meta that have the keyword “chat” on them or checking out the chat site (note that meta chat and stack overflow chat have different links).
- You can create a chatroom if you have enough reputation, but the only way to bring it to a users notice is by pinging them, and if you can ping somebody you already have a way to talk to them most of the time (exception: diamond moderators can ping a user who isn’t active in a chatroom).
- They may have a link in their profile, or be active in chat. Also, commenting is appropriate in that situation.
- Moderator flags (though for more important stuff than a disagreed edit), the per-site meta, and the contact is link for Stack Exchange (Note that this should only be used for very important stuff, and a disagreement about an edit doesn’t even come close).
