Disconnect visitors who are away
When the set time has passed since someone joined, it disconnects them if they're not looking at the chat page.
Settings
Enter a positive number in Time in seconds. 3600 is 1 hour. If you leave it unset or enter 0, the default is 2 hours.
Good to know
It checks only once after someone joins. If they're looking at the page at that moment, they stay connected, and it doesn't check again. Sending messages or moving the mouse doesn't reset the time.
The check can be late depending on the browser's state, so it can't replace a forced disconnect at an exact time or a security policy.
