You are trying to register with a Microsoft hotmail.com or live.com address.

Unfortunately, despite our best efforts we have been unable to get email reliably
delivered to these email accounts due to what Microsoft calls their Smartscreen filter.

The bottom line is that if we let you register with a hotmail.com or live.com address
there is a significant chance you will not recieve your registration email. Not only
that but the confirmation email we send does not appear in Junk, it simply evaporates
into cyberspace.

We have no issues delivering mail to Gmail, Yahoo!, AOL or anyone else, so please use
an alternative address.

Please accept our apologies for the inconvenience.

Kind Regards

The GP2U Team
