Scrivener has a brand new update available for free for everyone who bought it after August 2010 and for just $25 if you got it before that. Also! For those who don't know of Scrivener and are Windows users, at long last
they have a beta version of Scrivener for Windows. It's honestly the best writing program I've ever used and has so many useful components from the outliner, the new collections option which allows you to organize character notes/first drafts/plots, and the import webpage option for research. There's also a neat new quick reference window which lets you open up external documents for additional research in a smaller window so you can remain in the writing program. I completely recommend this program for anyone who does any substantial amount of writing.
My brother is in law school (he graduates in May) and he was doubtful about the usefulness of this program until he downloaded it. Now he adores it because it makes organization so much simpler for his massive research papers.
