this issue is still valid in Mango version 3.7,
have to use old UI to add emails.

Thanks Matt.
This didn't work for me. I've set the value to 5 minutes and after 15+ minutes everyone was still showing as Active in Events and I was able to navigate around without logging in again.

Hello,
We've got a situation when people are logging into the Mango and leaving their sessions running for a while, which is increasing internet traffic.
Is there a way to gracefully log out someone without restarting the Mango please?
Appreciate your help.
Elena
