OK! That's fine, Headisspinning.
But , according to Juan Viejo, the group settings later were changed to "open to all". Is that true? Or did just Juan make a mistake when he stated this? If the group settings were changed in that way a lot of people were outed, and still are to be outed. So far we haven't seen any message from Juan or Cedars that the group settings are changed back to secret again, but I assume that you can inform us about thad, Spinning.
Anyhow, as i see it, there is still a huge problem with the group. You have 100's of members that you have no idea of who they are. According to Juan there were some Pro -WT apologists in the group. Are they still there? In that case you still have the risque with further outings.
If you have a secret group you can't just let anybody join the group. Every new potential member has to be checked out before he/she can join the group.
Why not cancel the group and restart it......this must be the best way to act regarding what has happened.
