ChatBuddy is a small ui mod that tries to prevent mistells by keeping the chat channel that you want as default. No more thinking you're still in group chat when you had just /say Hi there! to a friend & then say (what you thought was in party) "this is the idiot I was telling you about"... Just set ChatBuddy to default to party, and all your chat will be there, unless you specifically change it -- or set it to guild, raid, even General channel.
