 Allow list administrators to use !HyperKitty to remove messages from lists
 or edit them (we'd also need to make security/user experience decisions on
 how, whether, and when to communicate on the webpage that messages have
 been removed or edited).

This issue taken from
 http://wiki.mailman.psf.io/DEV/Mailman%203.0?action=diff&rev2=30&rev...
 -- a wishlist/TODO for the Mailman 3.x series.

Comment:

I've heard substantial interest from systems administrators in this
 feature; the Wikimedia administrators of Mailman installations would be
 especially thrilled.
