Yes Domingo i agree about the descriptive sex part of your post, there is nothing more annoying than a "Clicker" jumping from pose to pose, and it is not just in groups  

, unfortunately  i don't about the  4 way, its hard enough keeping three people connected .
What would be a great IDEA is in a group session, if someone leaves  or is disconnected  if the room didn't shut down instead it  converted to a 1 on 1  with option to invite another member??
