Personally I am not sure if just having a listing would be useful. Being a forum it is about people communicating with each other, and when someone makes a post, they can choose to have their website linked to that post if they wish. There is a link to mine from my profile for instance, should anyone be remotely interested in it! I find that if I read a post that is thoughtful and interesting then I will look for a link to the posters website. And when you get Mr Angry or whoever ranting on, it would be good to have a link to their site just to see what their photography is like!
