Any good fan-created settings out there?

i hear RJK is releasing some stuff from his shared homebrew setting...

Well, I am always glad to plug Urbis, but if you have asked this before then you have probably already heard of me...

Thanks for the links, everybody -- especially the wiki I'd forgotten about that, so I went back and added links for my own mini-settings of Karthum (via Bronze), Kumquat Tattoo (see my .sig), and vs. Elves (for the vsM Engine).

As others have said, check the wiki link in the sig.

My pet homebrew is a collaboration between fellow ENWorlder Vrylakos and myself, and can be found here. It is by no means complete, and the HTML on some of the pages is less than professional, but it's fairly comprehensive (and comprehensible).
