It was a good move to add the Video and Monitor forums, and an even better move to get rid of requiring registration just to view the boards. (Requiring registration just to view boards is a 100% turnoff for most people. I know I sure despise it.)
So while all of that looks good, you still seem to have a problem with nobody reading and responding to posts asking for help. If you want your forums to be anywhere as useful and important as RGP or KLoV, that's gonna have to change. And if your tech simply doesn't have the time to provide free support over the Internet (which is very understandable, if that's the case), then perhaps trying to pursue such a set of forums isn't the best idea to begin with.
