Hi lizzy, and good morning
  
 Yes like the  3 arguidos site I am sure you will find lots wanting to join and take part.        The one thing that  perhaps you are aware of on msn , is the importance of members not showing their   e mail address .............this is the first thing  to cause trouble to a group security,   BUT i feel that the members from others news sites joining  will be only too well aware of not displaying their e mail address in their profile 
  
 regarding your question ref private, maybe this is an idea to think about, a little sooner thyan you would normally..........I dont really know, given the present situation.............My other groups dont have the hassle of these troll  type  people etc etc
