Chat rooms should have some kind of page that captures all the essence and go-to questions that can often come up, but aren't easily searched.
A reference point. A one page wiki.
The page should be editable only by the room owners, but visible to all that have normal viewing access.
This would allow for private moderator rooms to have a quick list of common scenarios or situations and their answers, that might not be good things to post on any meta, even if obscured.
Or they can have the room's few golden rules, because the room description doesn't allow long messages and pins that are constantly being repeated are constantly being repeated. Or who to contact on the team for various things.
Info currently gives you the overview of the whos and the whens of the room, but a one page wiki can be like the guiding hand or Teachers' Editions.
It could sit right next to that "info" link, something like "real info" or "room faq" and any changes get pipped into the main so that you can all know what's going on when any editing has been going on.
It could even be shoved into a new user's face upon their first entry into the room so that they can ignore it like they do all FAQs.
