do I have to log out or log back in to continue with these lessons? one of our sons, Aaron aka Mitz (RIP), taught and helped me with a lot on here, but lost all of it when I had to restore my laptop. This was before windows 10. he passed away in 2015.

As long as you are logged into Instructables, you should be able to access all of the lessons. You could try logging out and back in again though just in case. Let me know if it still doesn't work.
