Don't get me wrong, dotnetBB is a great system and I use it in another site. However, for a standalone bulletin board system, with more backend control, vB was a better choice. Unfortunately there are no importers so the old data will have to remain until vB comes up with one, which I doubt they will. We had to make a command decision early, although nearing 2,000 members on the old system, it was better then when this site crosses 20,000.
