This is a waaaay old thread.
Threads is pretty different from Classic. It's a different product by different authors... so it'll never quite be classic... and most Threads users wouldn't want it to be.
You should have come by here or played with the ubbcentral demo board to test it out before you made the big switch.
Although most classic boards that I visit are pretty slow, yours sounds pretty active. Your users have to notice the speed improvements with threads. I like some of the features that Classic has, but (from a user standpoint) speed is a big issue on any boards I visit. That is one plus that should be too good for them to ignore.
Most Classic -> Threads conversions are a bit tough, because it's different. People are resistant to change in their messageboards, although I've worked on dozens of converted sites that are now loving it.
Your users would have been equally "shocked" if you'd have gone to VB... because it's different. But they should settle in with time and your site will grow with the added capacity.
