Huh, I seem to have missed a lot. Accursed odd sleeping patterns.
I think my only concern is that whatever happens with the IJ s_d shouldn't be made unable to take back, in case things don't turn out well (I have no particular reason to think they won't, but i'm not really an optimist). Whether it's handed over to people (should they be interested) or simply closed to new comments or whatever, it might be a good idea to leave it up and running for at least a while after this goes through, so there's a backup in case things go sour and stragglers can find their way to the new place. But i'd bet you probably have thought about that already.
