As cellarius says, its part of vB 4.2.0, you just need to turn it on in the options.

How can I change the time that it tracks users from 24 to 48 hours? I think it might help me in getting a better average of members. I know you say it's not an option but what would I change in the code to make it a custom time.
It's currently set as a rolling 24. It is working fine after all this time.

Is all we need to do is change the
$cutoff = TIMENOW - 86400;
to what we want?

Thanks in advance

Never mind, it worked. Now I can adjust it as I see fit.
