If you haven't already, its worth checking out the shemale groups on Yahoo. Because the adult groups are not included in the search directory they can be difficult to find.
Some groups are more active than others but its worth having a search round.
You can find groups that are solely devoted to various babes - like Raquel Fox, Nefertiti, Gia Darling, Allanah Starr, etc.
Here's some I've found..
