A friend of mine tried joining the forum, and he wasn't able to cause the verification for recaptcha said ERROR for site owner:
Invalid domain for site key. He sent an email to the 'contact us' email address that is listed at the bottom part of the forum and received an automatic reply saying "Your message wasn't delivered to [email protected] because the address couldn't be found, or is unable to receive mail." Is there anyway to get this straightened out?
