Yes, but, as Rui has been trying to tell you, you never completed the installation as you decided to install Active (Logged In) Users instead, you'll need to finish installing Active Users before you can do what you want.
Search is your friend “I was having a mildly paranoid day, mostly due to the fact that the mad priest lady from over the river had taken to nailing weasels to my front door again.”
So, would there be a reason not to have the timeout value set to say 5 minutes? Or even 1 minute? The only thing that happen is that the users dissapear from the "active users"-list if they spend too much time on a single page?
And nothing else? If that's the case there is no issue for me =) If someone is spending more than say 5 minutes on a single page they aren't that active imho.
