Comment 1 for bug 552603

Would this apply to all email-registration attempts, or would it be somehow restricted to proxy-migration scenarios? In the former case, this proposal would definitely address Bug #551906. But, Psiphon accounts hold more state than just an email address, right? What about existing homepages, bookmarks, locale settings and accrued-invitations on whatever account was previously associated with the email address in question?

Also, in this scenario, we are assuming that the email-validation request reaches the user successfully (even though the account-migration email did not reach him at the same address). Does that give us the opportunity to do something clever? Like include the associated account-migration information (and link) along with (or instead of) the email-validation request? Perhaps something like...
