Adam, you're doing a great work here, one that a LOT of people are really benefiting from. This is going to go a long way to helping my group (that includes a couple Shadowrun newbies) settle into the game.
I understand you aren't comfortable with accepting contributions for Chummer itself, I get that. You are standing on the shoulders of those that went before you, those that designed Chummer originally, those that invented C++ and XML, even the forums here that let you distribute this excellent work to the widest possible audience and also that politician that invented the internet itself.... It gets a little silly after a while, but I have a lot of respect for your humility and professional integrity. As I understand it, you don't want to take credit for the relatively small contribution that you've made. That is actually pretty damn cool.
Here's the thing though, the old Chummer is not useful to me. It never really was, either. BUT all the work you're doing now IS what's making it useful to me and (more importantly) my players. Certainly Nebular and these forums and that politician and those other guys deserve credit for their part in enabling this alignment of the stars, but each of those others have already got some donations or funding or whatnot from whoever is/was backing them. It's your turn to get some help, even a little for the good work you're doing, from the people you're helping.
So *please*, let me buy you a $2 pdf so you have the material you need, or a beer (for optimal coding!) or a bottle of tylenol while you debug. You're doing ALL the work and I'm getting all the benefit and I want to help too, I just don't code. Besides, all this pent up gratitude is starting to ooze.
