I plan to finally upgrade FOB to Drupal 7 in the next few days. At the same time, I will move hosting back to my house from work, as my bandwidth here is enough to handle it now.
Moving to Drupal 7 will enable modern anti-spam, which should allow anonymous comments and reasonable user registration. It may have other benefits and drawbacks yet to be determined.
While the move is happening, the site may be down for a while. Apologies in advance. (B)
