What's to be shy about, no one knows you from Adam, just go with the flow, no need for an essay like nightwolf, ( and that's not a criticism, I like reading his reviews) mine are longer than his , but I spend an hour shortening them, even I'd fall asleep, forever would still be wanking ! But just do a couple of short ones to get a feel and your confidence will grow, and you will not feel the pressure of not doing any, you will feel freed up and liberated, and you'll enjoy this site all the more for it.
