@YemonChoi To say something more useful than just hello, I'll mention that if you wanted Category theory and Banach spaces to be unfrozen, this is one of places where you could find a moderator to do that. But I assume that the room was not intended as something for long term, just for a one-off discussion in case somebody joins in.

I should perhaps add the links to meta.stackexchange.com/tags/frozen-rooms/info and How do I unfreeze a frozen chat room?

@ParamanandSingh Haha 400 is a drop in your bucket of rep. It's not the rep that I was concerned with anyway, but rather the explicit signal to people who care about site quality that they will be targeted.
