While editing our help/on-topic page at Engineering.SE, I noticed that the boilerplate text uses a $SiteName variable rather than hard-coding "Engineering Stack Exchange" in the page. That's a nice feature in case the site name changes. There are hints about other potentially useful variables in a few existing MSE questions:

However, I could not find a definitive list. What variables are available to moderators when editing a Help Center page and what do they do?

    I sent over a feature request to have these listed in the side, following up on that.

This is something we addressed internally by giving a list of variables in the sidebar of the editor. It was made visible to employees because, at the time, none of the moderator-editable pages contained any of these variables, or at least we were pretty sure they didn't.

That's not the case now (obviously); however, I believe $SiteName is the only one you'd have to contend with as a mod unless circumstances on your site led us to make additional pages in the help center mod-editable. This is unlikely to happen, but not impossible, so I'm dumping the list here for the sake of institutional memory:

MetaUrl: The URL to the per-site meta
SiteName: The Name Of The Site
SiteShortName: The short (canonical or botique) name of the site
TeamEmail: The email address support requests sent from this site go
Topic: The site topic
Year: The year the site was created
Audience: Who is this site for?
ChatUrl: Chat URL for this site
BaseWebsiteAddressBare: The base address of the site (no http(s)://)
BaseWebsiteAddress: The base address of the site (with http(s)://)
Privilege-ModerationTools: Rep required for moderation tools
Privilege-CloseQuestion: Rep required to close questions

You should not need most of these. Rep thresholds are only variables because we can and (very infrequently) do slightly adjust the levels at which certain privileges are unlocked on certain sites. The rest is pretty self-explanatory.

I'm going to re-visit this and see if I can just get the help turned on for mods too, even if only a few of the variables would be of any practical use to you.

Sowwy about 'dat! Pretty sure I derped when I said 'mods shouldn't need this'. It's not that they're seekrit or something, it's just that we like to keep the amount of clutter that we push at you minimized whenever possible.

  • Rep thresholds are actually pretty variable. Consider differences between private beta, public beta, and graduated.

  • @Scimonster Not only that. As far as I know, the thresholds can be manually adjusted for specific sites, to support good moderation and/or community build-up.

  • Judging from the current Variables list I see as a CM, it looks like a few of these (CurrentTier, SiteImagePath/, CommunityLeaderName, and CommunityLeaderEmail) have been removed from that sidebar.
