lpp....thanks again for your help. You got me on the right track, and I have since figured it out. But the procedure is so different from the way it *USED to be....that if you hadn't provided some screen shots to get me THINKING differently, I might still be stuck!
For those interested in figuring this out...it's really quite simple.
Just click on and select "My Profile", and then "Collection". Then, near the top, just under where it says Collection....you'll see a line that says Add stuff to your list! That's where you type the name and select the option presented. Once added to the correct list (Collection, Owned, Tried) you can delete it from any "PREVIOUS" list.
Hope maybe this helps someone like me who was having difficulty figuring this out.
