I re-enabled the option to approve all new sign ups cause even though I have recaptcha, spammers are still getting into the site, and spamming, so all new users are supposed to go through the approval process, however I am not sure if that applies to Facebook sign ups. If so, message me on facebook, Joseph Slabaugh, and I can approve you.
You can now use your Facebook to sign into EX-Amish Forum Version 3.0! Note that you should include something about Amish in your application, as I got so many spammers that have weird messages as their bot created applications that I have to weed through to find the legitimate ones. However, I have found that also if you sign up via Facebook, then I have no such issue.
