It would be useful if there was a mod chat built into the website, as it would make contacting all other mods/verifiers at once for questions and such more convenient rather than needing to contact each person individually.

In some of the Discord servers of games I moderate, we have a hidden "mod chat" channel which is open only to moderators. That way it is possible to contact and talk to all moderators in an easy way.

But I agree this is needed on the site as well, not all games or users have Discord.

This would be nice right now, because of the problems with private messaging.

bold assumption that a mod chat wont have the same problems as private messages
