Ric,
The technical tips are permanent residents of the website. The "dance lesson", on the other hand, is more of a dynamic element which changes every month. This keeps people coming back frequently to see what's new, and by removing the old one, we get a chance to compile them on a CD and sell them, to make back some of what we spend on this website.
Or at least, that's the plan. We're already selling the previous variations. We just don't quite have enough lessons yet to make a CD. I'm hoping to have at lest ten or twelve on a CD. So give us a few more months, and all of the lessons will be available.
Sincerely,
Jonathan Atkinson www.ballroomdancers.com
