I hope we get the drrr themed chatrooms

We do. (´༎ຶོρ༎ຶོ`)

Is there not already a drrr style chatroom site? I remember there being one a few years ago, not sure if it's still up and running though.

There is, it's still up, but it only has ~150 users.
Direct Link to it or click "Chatrooms" at the top of the page and then "Drrr Chat Lounge"
