The members define the agenda so there is absolutely no set direction they're hell-bent on pursuing. Get yourselves signed up.
Zero pounds zero pence. It's a totally independent group and Bates has actually criticized them in his programme notes before for that fact. There's nothing to lose by signing up for free and getting whatever opinion you have across. In fact there's an awful lot to gain from it if every Leeds fan makes the small amount of effort required.
