Loads of “Iconic” Viners or Viners who would like to be part of a group can join one. You can have it so they have to send an application, send them a Vine.
There could be someting in the Channel Settings called “Group Mode” This means that the only the Group Creator can change the name, password etc.
It seems like a good idea for people who want to become larger on V2. Maybe vines with 20 different people in them - each camera scene randomly placed!
