Copy list to new account with comments and attachments

[GoGetter Pearson]

Hello! I will be grateful for any help to this problem.

I am a teacher and have some teachers working with me. We create a board with all exercises we need during the lesson. But the problem is that everybody who was invited  to this board can delete important information.

I have found the solution and created another main account. Only I have access to it. I make a board there, than I copy each list to our second board than on that second board I copy the list one more time with second account and for this second board I invite members to work it. But the problem is that if I have a link to attachment it doesn't open but in the attachment section it has no problems with openings.

What should I do? Please, help me!
