OK, for anyone looking for documentation, the best I could find was the Java documentation that W0lf has linked in the comments. Since Quartz.net is a port of the Java version, the documentation is similar enough to begin to understand some of the inner workings. I am developing some simple jobs to test and gain experience. Hopefully, I can contribute something to the community at some point.
Found another great place for information. The timeline starts by using 1.0 but then migrates to 2.0. But there is great info there and I can't thank the author enough for his work. Here's a link: http://jvilalta.blogspot.com
On another note, I was a little harsh on Marko Lahma. He is helping to provide an open source product that we can all use. I can't think him and his team enough for that. I do have a peeve when it comes to help requests though. It takes as much time to answer a question as it does to critique it. Why not just answer the question? Anyway, Marko, I apologize for being brash. However, finding time to update your documentation would be extremely helpful. I will contribute what I can as I can.
