Well, so the guild I am in is in default, and that's mostly because of the idle players in it. My main suspicion of the idle accounts is because of the Spiral Sallet hat in tf2. Some people, like me, play the game at first to get it, but get totally hooked. But some people get the hat and are never seen again. Since I am an officer, I would like to remove many of the idle accounts. But, in order for less confusion, I would like to contact them first by Steam to ask if it is okay, if they don't play, or anything else. But, Spiral Knights usernames are different from their Steam counterpart, so, I don't really know how I can find their steam account.
