Draco, we'd be more than glad to have you. We play matchmaking pretty much all the time. However, right now we are working on getting people to play more often so we don't always have a ton of people online. Me and Glory have been playing nearly every night though. What is your gamertag? Myself and Glory will look you up and once you are in the Clan everyone's account names will be right there.
About the other people on your account thing, that shouldn't be a problem. We'll just let you send us a message first when you get on and we'll then know it is you. More members are always welcome. Especially Zel members.
