I am creating a forum using forum module provided on DNN. My client came up with a requirement saying that they want to be able to track user sessions  and see how long a particulat user( in most cases moderator) was online. I thought it's going to be easy but what I found out that DNN does not have any LogOut event at all. It has Login_success but no LogOUT_SUCCESS. How can I even measure the session length when the Logouts are not even being logged?

Is there any way to see the LogOut Entries?

Thank you very much for your reply sir,.I have browsed through all the ASPNET membership tables and I do not see any kind of Logout there. aspnet_membership has LockedOut but no Logoutdate . There is not way at all to track the log out time at all?? That is quite bizarre of DNN.
