Wesleyan requiring girls in fraternity houses

[Drolefille]

I guess that's what I'm asking, to my knowledge, most sororities (with houses) have some sort of residence requirement. Is this not standard with fraternities?

-no sorority houses at SLU and only the one fraternity house, however we do have a Greek dorm and though we've never had to, we have the ability to "force" people to live there to fill up our assigned rooms.
