half a workflow

  1. add a new mail address to your account
  2. verify it by clicking on the link you receive by email
  3. make the new mail address the default one
  4. remove the old mail address
  5. logout
  6. create a second account, using the old mail address you just freed
  7. logout
  8. login with the old account (new mail address and the old password)
  9. ask everyone that has already assured you to reassure you under the new account (the one with the old mail address)
  10. in theory you could now delete the old account (the one with the new mail address). In practice I do not know how to do that.
