The Grand OGL Wiki

It's been a little while since I last plugged The Grand OGL Wiki.  Mark Gedak is doing some excellent work keeping the regular additions coming to the site.  If you run a d20 type game, you'll find tons of new monsters and spells among many other inclusions available there, all free for the taking.  And if you publish, or just want to be part of the OGL community in ways that enhance it for everyone else, definitely check things out there and be sure to follow the OGL when producing your own content.  If it is all up to snuff with the license, he could even use some of it there for the archive and make it available for everyone else, too.
