CR Oldham requested a change to allow an administrator to convert persons into users. On a similar theme, I've submitted a patch which automatically converts persons into users when they register. The user-new pages look for a person with the given email address, and load the name into the input fields. The acs_user__new sql function now only creates the person if necessary, otherwise updates the existing person's object type to 'user'.
