I think spammers have created bots that can figure out the captcha automatically. I received registrations like crazy and had more than 600 users to approve today… out of which I only approved 5!
The bottom line is that if you or someone you know has registered and wasn’t approved, you were rejected. This wasn’t done on purpose so just try to register again.
Best way to get approved for sure is to register and drop me an e-mail.
