1. So I cant find the option to make it possible for users to post without having to register and login. Like you have it on the demo site.

2. Also when you are not loggged in and you try to submit the user gets:

Oops, you've encountered an error 403
It appears the page you were looking for doesn't exist. Sorry about that.

Shouldnt at least there be a message thats says you have to be logged in to register?

3. I see there is option for comments, is there a way to add facebook comments instead ?
