@flazepe: It can be the same if you edit the old account first. We usually just put .old on the end. Just be aware, if you reuse the email address for someone, there's a chance they may not be able to download their backup when it become available without assistance from us. When we load the backup system, we copy the email addresses from the accounts table into it. If the email gets changed to example@gmail.old before that snapshot of the accounts and email addresses is made, the invalid address will be loaded into the system and their backup request email will never arrive...
