Hey Bogdan,
I am not sure on this but I think the system doesn't allow most documents to be edited concurrently. I remember seeing "Currently being edited by...." on some of the documents. Can you tell me a little more about this?
As you correctly said, the methods I mentioned work for the current document/user only but I think it should suffice Phan's requirements.
In any case, he has two ways to go about his requirement now.
Thanks
Devesh
