Movin' on up! I'm probably going to be moving the site to a new server today this coming week, assuming nothing else particularly awful happens over there, so expect the site to go into maintenance mode sometime today, and you won't be able to log in.
As is usually the case when moving to a new environment, there will probably be some instability. Don't Panic! If it's something really awful, just note it in the forums, and I'll get to it - probably not immediately, though - I'll have a lot on my plate the next few days. Be patient, please (:
