[Plugin: Facebook Registration Tool] Plugin Defintely not working

This says compatible up to version 3.05 of wordpress and most people are on the new version now of 3.1 and let me tell ya i wasted my time trying to install this and get it to work…. it doesnt work at all on version 3.1 if you insert your app id and app secret it saves it but then when u go to try to login the login page theres no facebook login at all …. all it says is password has been sent to email address and i didnt type anything in….
