One thing I noticed about the facebook registration is it doesn't create a password for your account. IOW, if you register to farriersforum.com with fb you will not be able to login using your username and password. The system will tell you that you don't have a password and will create one for you and send it to your email. Or when you login to this site with fb you can scroll over your username in the top right menu and change your password there. Hopefully this doesn't cause and problems with anyone.
I think that if you are going to have any kind of connection with Facebook on this site that Facebook ought to pay you something for the privilege.
LOL! People hate registration forms. FB registration make it too easy. I would like them to pay me though.
