I accidentally added the entire ШколаЖизни.Ру collection to my lessons. I was hoping one of you could tell how to get rid of it in one fell swoop. I do like the collection but it’s blocking my access to my previous lessons. Any suggestions would be appreciated 
@CHL - There is no way to remove an entire collection from you My Lessons list. You can try either using the search field to find previous lessons or changing the sort order of the list using the controls in the right sidebar. If you sort by recently opened, you should be able to find the previous lessons you were working on.
Thanks!
There are a few things in the works, just be patient.
