What counter / user tracking service / script do you use for your network?
 

How do you keep track of your website stats? What script / service do you use? I have more than 30 sites and I do not want to set up an individual statistics-account for each of them, but I want to have them all tracked separately.

So far I have been using xclicks tradings script for stats but they've started suspending sites that do not actually trade traffic.
