Is there any community based set of rules for 4e dragonlance yet? It doesn't look like wizards cares too much about dragonlance as a setting. I'm looking for something that details the various knightly orders, wizards of high sorcery, new feats, etc. I would think that by now someone has made a pdf that's good to go.
Not yet, no. We've done some conversions over at the Nexus and on Dragonlanceforums.com.
I can't speak for anyone else, but after putting so much energy into converting everything to 3e, it's kind of hard to turn around and do it all over again for 4e.
That being said, I would like to offer an invite to the members of this board to come over to Dragonlanceforums.com to talk about 4e conversions.
We've also got some folks talking about Pathfinder conversions if anyone is interested in those.
