I want to add a new email address, but it says it's already in use
The problem is that you've created two different accounts, each with a different email address. In order for you to have both email addresses on one account, the other account must be deleted. To allow us to do this, we need you to send an email to firstname.lastname@example.org from the email address whose account you want to be deleted (NOT the one you want to keep), giving us permission to delete the JobSlinger account associated with that address. We need this permission to be sent via email (and not a support ticket) to verify that the owner of the account really wants it deleted.
