Beigeldog - I'm relatively new to posting here and I don't think I am able to do a PM. I wanted to get a feel for the boards here.
There is a lot of information on SI on the Microcap Kitchen thread. A couple of posters have given detailed articles on both how it works and also the list of companies.
If you can't access that, send me another note and I will see if I can find the posts from SI.
