Now we're running the shiny new PHPBB3 version and I hope it's a lot friendlier interface wise. I've just completed the conversion process and a few tests. Lots of advancements under the hood. Functions like password updates/reminders and notification emails should be a WHOLE LOT smoother.
Style-wise... I've got nothing as yet. I'll poke around a bit, may try out a few options. If you've got a preference, speak up!

Edit: Here's the phpBB styles database. Since you can select the one you want in your user profile, I can just download a bunch and you can pick what works for you. Just let me know.
