It auto changed to "Awaiting email confirmation"
But lets say that members want to make this on purpose for there reasons.
And since his first email was ok, this is some issue.
It would be a good thing that he stays verified with the old email, if he wont
verify his new email. As you called seems there is no other way.
I don't know if is out there a modification that could take control..
and after 24 hours last email comes back.
Thank you
