Where did my other added lists go? I had 3 set up. Now I only see the primary list.
I'm sorry you lost your lists! No matter how much we've tried to publicize our move to a new catalog system in the past month, there unfortunately were people like yourself who didn't hear about it.
We'd recommended that everyone save their lists as they will not move to the new system. I would save the one you have remaining ASAP, as the old catalog (and list) isn't being updated and soon won't be available. See the bottom paragraph of the page linked above for more information.
With the new catalog in place it will be even easier to make lists and organize information about your account and reading preferences with an updated, modern web interface. I think you'll like the changes.
Once again, I apologize for the inconvenience.
