I just migrated from PHPBB to Simple Machines Forum because of all of the hacking and spam bot accounts I was getting on the PHPBB boards. I'm not sure if SMF is any more secure from these things, but we will see... If you have any issues with your moved account or using the new boards please let me know.
Also, the new URL for the forums is http://forums.gillius.org/, so please update your bookmarks. I will try to keep that URL as permanent as possible, however URLs underneath that may change if the software changes.
