[rt-users] how to remove watchers

[Nick Kartsioukas]

If you're wondering about the other two email addresses listed for Pam
and Veronica, if RT sees someone CCed on an email that comes into a
ticket, I think it captures that and keeps it handy so you can quickly
select from the dropdown to add that user as a Requestor, CC, or
AdminCC.  However, they are not actually currently a Watcher of any
type.
