With lots of trial and error I fixed some issues with the Drupal contributed email notification module. See http://drupal.org/node/view/8964
You'll notice that I'm showing a certain clumsyness sharing my patched code, but that's because this is my first time contributing code to a larger project. I'll have to look into CVS and such. Needless to say, I'm very proud either way!
In short, if at some time your drupal goes haywire, from now on it just might be my fault ;-)
Next up in my drupal work is the archive.module, which is part of the core of drupal! Let's see if I can make my own patch here
