I was just going to inform you that there is a Uservoice suggestion called [Global Chat](
http://warlight.uservoice.com/forums/77051-warlight-features/suggestions/1092123-global-chat-room?ref=title) but when I went to get the URL for you it said that its status was 'completed.'
It said that it was under the Community tab but I can't find it. I assume that it hasn't actually been implemented yet? I hope I'm not that unobservant, but sometimes I miss the most conspicuous things.
