Between yabba and phpbb I would go with phpbb. I've used phpbb but my last forum I used and I like SMF better then PHPBB. I agree with Lynn Terry about vBulletin , it has nice look and has more features then the freebie forums. So that would be the top choice if you don't mind paying for the license. We'll have to start a collection to pay Angelaaa's fee so we can know the truth.
