Fabulous! I don't think you can achieve what this extension does with any of the other ones I've tried so far. You can see exactly what every user does, and when. You can see when they log in, when they register, entry by entry. Full reports on this. Plus, you can make graphic charts about it to complete your analytics, even make rankings and such. Incredible add-on for any site admin that wants to know what's going on in the site and what users do, even know when admins login and what they do. Total control. Highly recommended. Great support too!
