I hope you didn't somehow accidently do what I just did. I managed to find all of the threads in the new location
and then wiped them all out. I had tried to " manage threads " the way we used to be able to delete subscriptions in the past. I checked the box next to the ones I wanted to delete, and thinking these were the only ones I wanted to delete I took the next step when prompted to and now I am " following" none. Oh well, not a major life problem by a long shot.
I kept my avatar and my signature so I'm happy.
