Regarding changing the email address on your forum account:

Note that the account will be disabled until you confirm the new address by clicking on a link in a confirmation mail that is sent from The Britboard to the new address. This is to ensure that a valid email address is used.

Note also that if you use hotmail or another free mail provider, the mail from The Britboard may falsely treated as spam. If you don't see the confirmation in your inbox, check your bulk/spam folder.

You will not be able to post on the forum until the new email address is validated.
