to elaborate a little bit, i was going to attempt to use this software mod called WP-United, but it was buggy, unstable, and abandoned by the original developer. someone recently has picked it up to further the development but it wasn't at a stable point for me to be comfortable enough to launch with.
we also decided to turn off registrations for wordpress because that would fragment discussion to two different outlets and the last thing we needed was yet another forum to manage and moderate.
we tried to use this wp plugin called wp2bb while sounded good on paper, had a few issues i was unable to debug; so it's been abandoned.. for now anyways. we're investigating other options. this is something we definitely want to make happen; it's just a matter of finding the right solution.
