We have been using Zoho Chat for some time for our chat room here. That has worked reasonably well, but I've wanted us to move over to something with desktop-client support for some time so that people can more easily keep the chat open in the background.
We were going to switch to IRC with v10, but as Zoho is currently down I have pulled forward our plans.
If you open the chat from our site you get a very user-friendly web-based chatroom.
Behind-the-scenes though, it is #composrcms on Freenode (yes– we're getting a little ahead of ourselves with the channel name ). You can use any normal IRC client to connect.
I hope to see some people on there . I can't promise to be chatty myself as I always have a lot on, but I plan to keep an eye on things.
