As most others have stated, activity in private groups is down. Although I think the nesting and newest to oldest replies posting may actually work better in the public forum, it's terrible for private groups. I have continued to be active in my groups and give the changes a chance, but I still prefer the b.old post order. It is just so difficult to follow a conversation from start to finish, which is essential for active groups. I hope that as changes continue to be made to b.next, members will return and activity will increase again.
