Activity Report for Professional Collaborative Version

Question:

Just curious if there is any way to see if a client has logged into their file or are using it at all ?

Answer:

After logging in, click 'Network' on the left toolbar, then click 'My Network'. At the bottom there is a user list with some basic information.

Then click 'Activity' on the same toolbar. On the 'Activity' tab, toward the bottom of that page there is a section called 'Recent Activity' that shows a list of new users and recent visitors.
