There's been another kerfuffle about copyright in the OSR. So, to reiterate and clarify: Everything on this blog is done under a Creative Commons Attribution-NonCommercial 4.0 International license. So are all documents that I've produced and linked to via it unless they have another explicit notice on them (the OGL or something) or are work for hire. You can read up on what a "CC BY-NC" license means here.
If you want to use something I wrote for commercial purposes (or hire me for stuff), shoot me an email at johnbell17 at Google's email service, and we can work something out. My main concern is not to scab on other people by replacing their paid work (or realistic possibility thereof) with free stuff, so bear that in mind.
