I ran a bridged phpbb3 board and decided it was time to eliminate the bridge and find a Joomla based forum. I searched and found Kunena to be a good choice as they offered a way to import my phpbb3 posts and custom smilies. Only downside to the process was it didn't do attachments. Oh well, I moved each one over 1 at a time, all 1100 of them. Once installed my users loved it and for me, a lot easier to manage. Also support and add-ons are top notch on there website. Best choice I made for my site!
