well we wanted a central login for our staff and admins so we made this, its no security risk. as at no point does it contain info that could be breached it just redirects to the correct area and if youre not in the usergroup of mod or admin then like i say it will redirect you to the url x it does all this in about 2 seconds of hitting the page sp theres no security risk i can think of.
its for non-vb pages but its more intended so as to creat a central login area, for folk who have remove the admin / mod cp links or for people like us who wanted
www.site.com/staff as a login, good for the index of a subdomain like staff.site.com
