I think you are banned. I'm pretty sure I've been banned as well, although the last time I checked I was indexed, just not showing up in the results. It sucks, because I'm on the first page in Google for all my keywords and phrases. Part of me thinks Yahoo has Google envy and banned me for spite. :P
I've been looking over our sites to see if there is anything in common and a couple of things pop out at me. Maybe we can hep each other. We both have title tags in our hyperlinks that are exactly the same as the text of the hyperlink. I do not think it is your affiliates. I have none. One other thing is at the top of your code there is an H1 followed by an H2 and then the table is closed. I use divs, but mine is closed before any other content too. Maybe there should be content after those, before the tags are closed?
