If you finish the 120 hours of free chat you can skip it, if not you can pause video chat and it shows as private.
I like to start out in free - it just gives me a little more exposure - and i like to have my 15 hours to quality for top attentive host - i get an extra 5% just for being nice a few hours a week.
Of course sometimes i can't deal with all the beggars and pretenders - so i pause it!
