That's all i can remember so far,
basically clubs and socs can't exisit without you buying access cards.
Even using toilets/banks/chemist/food facilities in Wentworth and Manning - building services also cost money
If they didn't exisit we'd all complain, like people at other universities.
so pay up and enjoy the ride
