Describe what you need us to do:
I appear to have two Hyperkitty accounts: one for my Fedora id (FAS: logic, "logic@fedoraproject.org") and a local login for my regular email address ("esm@logic.net"). I'd like to merge the two under my Fedora ID, if possible.
I saw a prior ticket for someting similar (https://pagure.io/fedora-infrastructure/issue/7026) so figured this was probably the best way to ask for it. :)

When do you need this? (YYYY/MM/DD)
Flexible.

When is this no longer needed or useful? (YYYY/MM/DD)
Open-ended.

If we cannot complete your request, what is the impact?
"Unpleasant user experience" probably sums it up. :)
