I have been unable to acquire the activation email.

I would like to add that I registered with a temporary email address. The address I registered with no longer exists.

You must register with a valid email address.

He should be able to update (or change) his email in his profile.

Is that true?

That is correct, no need for re-registration, once you have done that I can send a new activation code, just reply here :)

Activation complete.

Welcome aboard :)
