I've set up a wiki on the site to spur some interest in reviving the old book project (aka Project Goliath). You can access it here:
http://www.slinging.org/wikiFor people who aren't familiar with wiki's, the best way I can describe it is that anyone can go into it and make changes, make new sections, add pictures, etc. You really just need to play around a little bit (correct a spelling mistake, add a few bullet points, etc.)
You don't need to write production quality literature. Even adding a few bullet points, references, or ideas to a page is useful. Almost all are blank at this point. Just click on a topic and hit the edit tab at the top of the page.
