Change this forum email address

I maybe missing something fairly fundamental. How do I change my email address that I have associated with these forums?
Recently I received an email from the system saying that it was having problems contacting me. Within the email is a link to ( When I update that setting and click change I get a message saying that “You are not permitted to view the requested resource.”. Hmmm!!! It does not look like the update has gone through.

Many thanks in advance.

Please contact for assistance with this and we will get it sorted out. The users in the forums use single-sign on across properties and not just at the forums.

Thanks Smashingred. I have put a request in.
