This page explains the OGL and the controversy that raged in the D&D community in January of this year.
For the "swordsage" theory, as I don't follow the relevant threads, I don't have the faintest idea.
About the answers in today's post:
#1 should not be included. It's redundant with this quote, and even more so, with answer 2B in the Geekademia interview.
#11 should also be left out. It's not about the comic. Also, it's going to be obsolete soon enough.
I think all the others should be included, as well as the one about Wrecan being a Crusader.
