That sounds like a good system. I would love to read anything you'd let me, and offer constructive criticism if you want. (For example if there are shifts not well described in the framework. But all I have is some familiarity with Latin and Greek palaeography.)
Yeah, dranorter isn't my name, just what I'm used to being called online. It doesn't come from anywhere really. I wrote up a sheet of nonsense 'fantasy names' in middle school and just picked one. My email address is also under that name, at gmail.com.
