That group message is good and all, but it seems very inefficient at gathering groups quickly. I use Line chat with some other games and is a great cross-mobile device chat app. If you're interested, message me through Line (Ohmbrewer tag) and I'll create a Strike Team Kilo chat group. You'd be able to chat as we try to do in the clan message, but also PM people and create separate chat groups for raids/strikes/etc.
