I searched before I posted but I still might have missed the answer.

I created a group and made is closed. Now I would like to change that from Closed to Open and I cannot figure out how to do that. I did go to the Edit Group button on the group page but that only brings you to the Step 3 page of editing a group.

Any help is appreciated. I don't mind adding the people when they join, but it would be better if they could just 'auto-join'.

Thanks.
