I just finished setting up an older forum to run FusionBB. The install of Fusion went perfect without a single hitch.
I then ran the conversion utility included with Fusion to convert the site from UBBT 7.x and it went perfect except for one item. While it recreated the gallery, it did not pull over the images. I'll post that in the bugs forum.
Otherwise it again affirmed my decision to run FusionBB on all four of my sites.
"I have moderated and managed discussion boards since 1999 for various sites and networks, including a message board with millions of viewers for a top 25 internet company. FusionBB is shaping up to be one of the most feature rich and flexable message board programs available on the market. I am very excited to see the future of FusionBB, and convert over my two forum sites to FusionBB when available to the public!"
