I don't think this will be of much use, but I might as well put my input on this. If there is problems connecting, trying to get a match set up, then why not use Personal Message? That would be the best way without having to go in game, in my opinion. While I do see a use with this chat being used at a later time and date (when beta testing is over and there is a great amount partaking) then it could really be used for general chat and locating others in game. But until then, I personally think it won't be of much use.
