I am currently contributing to the Grand OGL Wiki (name subject to change) by stripping Open Game Content from books provided by Mongoose Publishing and placing it in the searchable online format. This endeavor should be pretty useful once we have more content up on the live site.
Give it a spin, see if you like it, and maybe even lend a hand. I am currently working on the Quintessential Cleric II book and hope to see it ready to go live in a couple of weeks. It would be cool to see Echelon on there, if it is deemed worthy of inclusion once I am finished writing it.
