Description of the issue: As an editor, I need to be able to reattribute a
comment I make to someone else so I can comment on behalf of Greenpeace
rather than with my own name. e.g. When I reply to a comment on a Post I
cannot change my name to the name of my office (from Kelli > to Greenpeace)
or IED (from Kelli > to Bunny).
I would expect if I changed the Name/Email to the same fields as an
existing Editor the comment would be reattributed to them.
This appears only to be possible if I comment as a guest; which means that
NROs will be forced to allow anonymous commenting on their site in order to
