This was my chat addon of choice while playing on Apollo 2 and it served me very well. I also had a good experience with chatter, but Prat seemed to work a little better. Super Clean look and just enough configuration but still pretty good right out of the box. 

Also supports features like alts, class coloring, shortening of channels, and getting rid of all the pointless buttons.

TESTED AND WORKING!
