I cant understand why the cam feature was brought in only for premium members. That way, you will only get a very few camming.
It should have been brought in for everyone, with the caveat that after say 6 months it will be only for Premiums. That way, if it was a great feature, more ppl MIGHT be prepared to pay membership to keep the cam feature.
I am a member of another site where the cams are free, loads use the feature, and there are loads of paying members.
