My yahoo name isn't showing up on the message board anymore. Is there a way to get it back?

I post some on the yahoo finance message boards. I've always been known as fineguesser. Last night I tried to post and had some aliases pop up as choices but they did not include fineguesser. The aliases were names I don't usa any more so I went into my profile and deleated them. When I went back to the finance page I had only one name I could use and it was one of the deleted aliases. I also play yahoo spades under the name fine guesser. The spades site is still using fineguesser. Anyone have any idea what is going on?
