This module is a greenhouse for Rules functionality – triggers, actions and conditions that could be included in the Rules module, but probably should be tested out and voted on first. Feel free to add your own ideas, opinions, examples and feature requests!
Note 1: I do not plan to make a stable release of this project. It is a greenhouse for building and trying out new functionality for Rules, and should always be open for new and untested ideas.
Note 2: The Views integration in this kind of broken. It will be rewritten, but that has not started yet. If you want to use Views to load entities into Rules, I recommend Views Bulk Operations. See the VBO chapter at http://dev.nodeone.se/node/984 for a tutorial on how to do this.
The usual. Download, enable. You will need the Rules module. (Surprise!)
