Anyone can contribute to PD

I still don't think you will be able to contribute with just basic syntax knowledge of c#.

Well, of course. I don't plan on ending there and have an XNA book planned next.

Then not anyone can contribute to PD, only those who understand the code and have programming experience...

You don't need to have coding experience to contribute, though. Simply filing in bug reports and testing the hell out of the game is enough contribution right there. Afr0 and the team wouldn't have gotten nearly as far if we hadn't pointed out the amount of network errors and graphical glitches that needed correcting. That's the beauty of open source.
