If you have a temporary Ricky or Johnny account that is using the same email address that your old Tommy account was using when he crashed then yes, your account will automatically be moved back to Tommy. If you don't have an account using that email address an invitation email will be sent to you. The way the invitation email works is there is a special validation code that you can click that allows you to create an account even if the server is full for the day. You don't have to reply to anything, actually the email comes from no-reply@heliohost.org so even if you tried to reply it wouldn't go anywhere, just click the link when it arrives.
