Post in Removing and adding a member
Hi Walter,
It is not possible to remove a user from the site entirely. If the old
account has been removed from all groups, then you can go ahead and
create a new account using her new email address.
There will be two site member accounts with the same name, but they will
have different email addresses associated with them, and only the new
one will be a member of any groups.
Kind regards,
Alice
