With this forum, you can register with Facebook, or register the normal way (use the same email address as you do on Facebook to log in) and then you can Connect thru Facebook (will ask to link accounts, check 'yes').

One of the good things about connecting through Facebook is you can have threads you start AND replies you make to different posts post straight to your Facebook Page. All you have to do is find the Publish to Facebook which is to the left of Submit new Thread and Reply (bottom Right)
