@usualhopeful, in the past few years women’s colleges have considered and adopted policies regarding transgender students. It has been discussed here. I think you should just google it, since they tend to vary in some nuances.
BTW, @pizzagirl, doesn’t Wellesley still have Harambee House? A white friend of mine was innocently taken there by her black roommate, who was from Surinam, at the start of freshman year. They were not greeted warmly, shall we say. Ooops.
