The forum is still undergoing domain transfer, hence the occasional logging out. There are a few bugs Flence is trying to work out, so please be patient.
As for posting inability, Flence had to shut that and the search down for a little while so it would stop overloading the server until he can locate and fix the code that's causing that. Things should be up and running just fine again in a day or two. Keep your eye on THIS THREAD to keep updated on what's going on.
