When I tried to log in to your forum using Facebook, your site said I could not log in, because my Facebook does not have an email Address associated with it. Excuse me, but yes it does.
Then I tried to register on your forum with a new account, and then when I put in my email Address, I was told that my email Address was already in use. And then when I tried to use that email to log in, I couldn't log in, so I proceeded to request a new password. Then I was notified that my email was not registered on the site. A total contradiction!
Also, why don't you have a normal way to contact the company, like an email or phone number?
