The Collaboration Session window will list all the users that are currently in the shared graph session as well as their status and the version of Maltego that they are running. Additionally, the collaboration window will list meta information about the graph session.

Shared graph sessions are cross platform which means Maltego XL, Maltego Classic, Maltego CE and CaseFIle can all join the same shared graph. However, graph size limitations in the different clients will still apply when in a shared graph.
