Hi all! When I created by account on Wikiapiary, I did not received any email confirmation, and when I click 'Mail a confirmation code', it throws me an error message:

WikiApiary could not send your confirmation mail. Please check your email address for invalid characters.

Mailer returned: Unknown error in PHP's mail() function.

 This may be an issue with the mail function. Please fix this.
Also, my email address is the same as the one I used to send this email.
