I kinda made a clan to see what it was about and now I want to join a real clan. The problem is when i go to the clan page it doesn't ask me to send an application. Do I have to wait to the launch to leave it?
As others have said, you won't be able to leave. I believe anyone but the leader can leave the clan by joining another clan, but I believe the leader is stuck in the clan until the official site/app/game launches on the 5th.
