The WordPress software we use for phatic.org has been upgraded from 2.9.2 Multi-User to 3.0. WordPress have decided to merge the standard offering in with the multi-site version so a few things may look different in the administration menus.
I have fixed most of the bugs I found, and enabled a new default theme (twentyten) which we are using on the main site now. Report any bugs in the usual way and good luck!
There are notes on setting up your WordPress site here.
