I had a mod once that allowed me to auto join a custom chat channel and filter it to what ever window I wanted. Now I can't find it. Is there still a mod around that does this?
Once you join a channel, as long as you dont /leave, you shoudl rejoin it upon logging back in. Then you can assign where that channels text appears by selecting the channel on each Chat Tab as you see fit.
Now if you are wanting to change what Chat can do, I suggest Prat.
