Yes we have almost everyone in our 4 USA elite alliances on the same line chat (about 120-150 people with turnover). It'll be hard to start a new line chat across alliances because each alliance already have their own. See how you go but if it doesn't pick up, you can join the USA elite community if you'd like. There's a group for every medal range and the goal is to get all 4 alliances in top 10. We already have 2 of them in top 5 at the moment. Most of the forum posters have joined USA elite now.
