As I understand it, the main benefit of clan over community (and the reason it was set up as a clan for OS) is that community chat never used to auto-connect. Now that the chat does that, I think that sways the balance in a community's favour.
Can anyone point out a reason why a community wouldn't now be a good option? Failing that, I'll get a community set up, and start pointing OS people in that direction.
(I guess a downside would be that we'd lose the OS tags so it wouldn't be as obvious when new people joined vs. people just being "outsiders"...)
