The create a new chat-room page likely doesn't get a lot of traffic, which probably makes issues with it have a relatively low impact, but this one should be fixed:
The text reads:
All conversations here are public, and they are logged and licensed under the same cc-wiki license as The Stack Exchange Network.
and yes, that is a link to the CC BY-SA 2.5 "cc-wiki" license that SE moved away from relatively recently (a.k.a. nine years ago).
Setting aside the questionable status of the recent shift to CC BY-SA 4.0, there's no sense in having this bit of outdated documentation around and unfixed.
As part of the recent, much saner approach to license indication for new and old content, how's about y'all fix this page so that it doesn't create further legal problems?
