I just released an outbound click tracker. This is based on some work I did on this a long time ago, along with My old Friend Phil Chadeayne’s original email notifier code (written in ASP around 1995). I’ve used some more advanced JavaScript than in the original version, modeling it after the way Google Analytics records clicks.
From the readme…
