bump cuz I'm interested, too.
I've had invision installed for about a year now, but no one really uses it that much. I managed to get the 2.0 download they offered before they locked up the free version, but I don't know what I think about continuing to use it and not being able to update it or get any real support. I thought I heard phpBB wasn't as good administration wise and didn't offer as many features as invision. Is that still the case? I'm thinking of changing hosts soon, too, so now would be the time to make the switch. Are there good themes for phpBB? I've got a set that I really like for invision...it'd be nice to find similar ones for phpBB. Anyone have any thoughts?
