Classroom IDs, lost in cyberspace?

Hey all,

I'm wondering if there is a way to view classrooms that I have created.  I'm notorious for starting but not finishing projects.  I may or may not have begun some great classrooms with collections of games that are wonderful for instruction, but have misplaced the Classroom ID.  Is there a way to view Classroom IDs created under my profile?

Classrooms only last a certain amount of time after their last usage. I think it's a max of 7 days.

But there's no site provided.way to see any still active classrooms you may have that haven't been removed. You should be able to use your browser history to see old ones

I'm pretty sure it's longer than 7 days. Thanks for the warning that they might expire though. I'll keep my collections saved in a Library.

I asked once and couldn't find the reference at the time I posted. I looked again and unless it's changed, it's two weeks after the last use.
