I dunno the show wasnt very good (it was aired on E4 in the autumn here)
The US girls didnt 'get' the British girls and the British girls didnt seem to get the US girls either.
Most of the girls didnt even attend Leeds Uni (quite a few were from the two unis here in Sheffield) so I dont even understand how they were going to establish a proper sorority.
They just dont have them here as everyone pretty much lives OFF campus even as freshers. I dont think the show had much of a following outside the first episode (they tried to get people to watch alongside using twitter, without much success), so most people wont have a real understanding of being in one. People are curious as they dont get it...
Also, like most 'reality' tv, theres very few real things about it...
I wouldnt stress.
