We're no longer accepting hotmail and msn email addresses for new sign-ups due to hotmail incorrectly filtering these activation email as spam. In doing this, the activation email is not delivered to the hotmail or msn address and so it is not possible for the recipient to activate their account.
While this will not affect existing members with hotmail or msn email accounts, new members will not be able to sign up unless they provide an email account with a provider other than msn or hotmail.
Apologies for the inconvenience. If you're looking for a free email account, we recommend Yahoo or Gmail.
