BuddyPress.org

I don’t see why it would cause any problems unless another twitter plugin also created a bp-xprofile field in which case there would simply be an annoying duplicate field.

One possible way around such an issue might be to allow a site admin to simply nominate a new or existing bp-xprofile field, that way if another twitter plugin created a different field you could just nominate that one.

Of course, I could be vastly over simplifying things here.
