I'm looking to add some functionality to the module for my own use.  Basically my company wants to know when a client downloads one of our trials, so we'd like the module to email the user information.  Only registered users can see our downloads so that wont be a problem.

I assume I can enter the code for this into the same spot as where it tracks clicks normally, and use that very same data.  Where is this in the code though?  Which file?

If there is a better solution to this I'd also love to hear it, thanks in advance for any help! :)
