Comment (by teeboy4real):

 Hello @imath

 I really like this idea and I would also like to add suggestion of the
 ability to control registrations based on a set threshold or the number of
 already registered members. I would love to share this code below with you
 so you can review it and improve on it. Adding this to core would be
 really awesome.

 Thanks
