After searching, gamefaqs is the new site to use for managing your collection. MUCH better than stacks, and might even be better than the old gamespot lists. Can even link back to reviews on gamespot. A search on Alexa will show you clearly that as gamespot's redesign has obliterated their internet traffic, gamefaqs' traffic has begun to rise dramatically starting at the same date.

Tip : put your stacks in "edit" mode and as you put them into gamefaqs, remove one at a time from gamespot. Save the gamespot list periodically as you empty the stack, because its buggy, and certain actions can cause the save to fail. Convert to an "unordered list" before you start to save headache.

Good luck!

I for one am looking for a new site to use. If they don't know enough to not destroy the site, I don't expect them to fix this. I have checked out grouvee, which is OK, as well as VGCollect. Looking for any other tips.
