Unfortunately the Blackberry Storm forum is this way as well (little traffic). I think it's due to the fact that many people use the forums at Crackberry, BlackberryOS, Blackberrynews, etc. The thing about the LG Dare, Voyager, and other non-smart phones is there aren't many large news/forum sites... so people that want help flock to the these forums. But for blackberries, and even the iPhone, traffic here is very limited since there are so many other (and much more well-known) options..
As for the new posts problem, I'm not sure. We'll have to have an admin look into it.
I was thinking the same thing Rob. Non-smartphone forums seem to flourish and work well. But with websites that have been around a long time, and devoted to berrys, like crackberry which I have come to love, it causes low traffic to some other places like this. I still check back here every day though, usually without any new posts.
