Maybe she isn't making porn anymore, or maybe IAFD isn't keeping up on all of her projects. I've done searches on that sight before and it doesn't always show everything. I do think she still tours as a stripper, though.
If you Google her name, her official MySpace page shows up. She has her dance calendar on that.
If someone wants to maybe they can tell if all these Freeones Forum links include newer stuff:
