The Gatecrashers development team (ok me) are big fans of Scrivener.  I can’t say enough good things.  As a tool for building a storyworld I haven’t found anything better (though we are building a pretty dope Filemaker Pro database – more on that later).

In the meantime, check out Scrivener over at Literature and Latte.

This is a blind recommendation, but here’s a blog I was just pointed to that claims to be “Everything Scrivener.” Give it a whirl. EverythingScrivener
