Will you be upgrading this forum to phpBB 3.1 when it comes out later this summer? 3.1 includes a revamped extension system as well as giving an RSS feed for each post (which will REALLY help with FM).
Possibly, it depends on the risk factor of upgrading. Ive seen lots of phpbb posts about upgrade problems and I dont want to spend a few days with the forums offline while we fix them.
One thing that is really nice about it is you can enable Facebook login with one click, and you can get a ton of other sites through plugins (no more going through and hacking source code - everything's now in plugins).
