A Slack Chat For Animation Art Collectors

I know there's already a chat on here, but here's another one that a lot of us are using:
http://cels-chat.herokuapp.com/ (It may take a few minutes to receive the welcome email after signing up.)

"For those who haven't used Slack before, it is a multi-platform collaboration and chat program. It's very easy to use and has many of the same features as IRC (plus a lot more). You can share pictures and video directly in the chat, and the chat itself is continually stored (so you can go back and read what was said even when you weren't there). You can use it directly in your web browser or they have clients for Windows/Linux/Mac/iOS/Android/etc."
