The EK forum should be for EK crew who are in the company. It is a great place to discuss EK internal topics away from those who are no longer here / sh*t stirrers!
I would recommend those at EK who have not joined to sign up, use another log in name if you want ie use one for EK forum and one for outside forums if you must. That way we can keep the usual stupid 'mines bigger than yours' to the ME forum and other more useful stuff to the EK forum away from the gaze of management!
