I will be conducting a test migration of this forum to phpBB 3.0 (we're on 2.0.21 right now) this weekend using a copy of this forum's database. If all goes well, starting next week we'll be using phpBB 3.0 for good. It is my hope that it reduces the spam problem we have right now. The measures I've been using seem to work rather well to contain the spam in that one subforum, but with the new generation of anti-spam technologies in phpBB 3.0 we might get lucky and not have any spam in the first place.
I'm announcing this now in case anyone has any objections or input. Let me know what you think.
