Better public stats?

[cmiller1014]

Is there a hack that will give us some info such as activity stats? I have members that want to see this. IE:

1. Within the last 30/60/90 days (these are your active users, whether or not they posted)

2. Only once (curious lookers who may not be back, -or- people who didn't understand how to use the site)

3. Less than 4 times, and the last time was >45 days after they created a membership (people who gave it a try but decided not to participate)

Anything like this thats easy to install and gives a good breakdown?
