GM Resources

I created this page mostly as a reference for myself. Maybe you'll find it useful as well. This is a living document that I will continue to update as (a) I have time and (b) I find new great stuff I want to remember later. (The asterisk after some entries are just things I want to return to and read more closely - reminders to myself.)
