PLEASE...
I am a regular visitor, at least 3-4x per week, for some 4 years. But I'm starting to lose interest, and increasingly, I'm visiting less and less often. Why? Personally, one of the big draws for me, and evidently quite a few others, is the Variation of the Week. And there hasn't been a new one for well over a YEAR, despite promises they are coming "soon."
I guess they are a lot of work. You seem to be working on a lot of different things on your site, improving. That's to be admired. But -- I think the endless re-runs are something that is much more in need of fixing than the bulletin board. Perhaps others feel differently. But it seems to me that the variations, from a marketing point of view, are likely your best bait for bringing people to your site -- especially more experienced dancers, who are the ones more likely to give aid and assistance to beginners over your bulletin board, etc. -- that is, the ones who are most likely to help your site grow.
Just my 2¢ worth
