I'm not sure. There are dorms such a Plie, which have posts from 2005/2006 on the first page of their dorm pages. Which shows how inactive the dorm has been for a while. I think new members to this dorm get put off by this and don't bother coming back.

I don't think Plie Dorm even had a head!

Maybe for the short term 2 dorms may be better just to keep things active and attract to members, that way at least there will be some organisation and activities going on.

But to be honest I'm not sure. Each dorm has their own way of running things and like you have stated previously there are usually times of inactiveness,etc.
