Looks nice.
Every time you click for "Free Chat" you get a message saying
"Model Name is in private. Don't you want to sign up now and join the fun?". Wouldn't it be a better approach just to tell the surfers that they need to register for a free account, instead of using that message? Because obviously not all of the models are in privates. Of course, you know better, you've tested things, etc... but it might look untrustful for the surfer...
