We are running a *very* heavily modified version of vBulletin 3.0.3.
Upgrade to vBulletin 3.6.0 Gold.
Port *all* hacks/modifications/integrations over (even the broken ones) and make sure they function. If you're not intimately familiar with [url removed, login to view] this job's probably not for you.
Integration with phpfox.
Service providers with references to past work done on vBulletin installations are preferred.
