"During my years I have written quite a few triggers for Batmud. Now most of them are available to the general public. Feel free to use them. One of my key points has been to make the triggers easy to use. So, if you have questions, please ask, but read the disclaimer first. Also, inform me if the triggers don't work with TF 4.xx, I might do something about that (triggers are written for 5.0b7)."
