How to share sub projects?
I made a project A....and then I added 3 sub-projects (A.1, A.2, A.3).
I share A with my friend. He doesn't see A.1, A.2, A.3
So I had to shared also A.1...and then share A.2...and finally A.3
He doesn't see the tree like I see it... but A and A.x are on the same level.
Where I make mistake?
