Honestly I don't think it's a big worry on how many are in a room together, for me, it's more that there's only 1-2 admins online anymore in a 24 hour period, and if they are, they're idle, and other admins don't get on chat at all usually. When you guys use other forms of communication (like the forums & discord) it doesn't.. show that to the community, they don't SEE you interacting or active within the community, as most posts on the forums aren't to interact with others, but personal posts, or towards friends. It makes you all seem very closed off and hidden, which is why I think it's more important to increase the administrative activity on chat, since it's probably not that busy, forum wise with reports I'd assume with how slow chatlands is now(correct me if I'm wrong however), which to me means you need to increase your activity within the public community, since there's a required activity amount, or at least, there should still be.
I voted that it's fine w/ many admins active, because honestly, administrative presence has been lacking for years on the chat itself. I want to see the administrative leaders of this community, actually present on chat, and if that means sitting with a full room where other admins are already at? Then do that! Being present is probably one of the best things you could give the chat community.
