Well, I've never collaborated for content on my site, but I think it might be a great idea. One caveat is that the site is for the general public, and many grade school, high school, and university students use it. I'd like to keep it at that level, and away from presenting very advanced topics.

Unfortunately I don't use skype or icq. Email is still the best way to reach me. I'm not sure why author@ancientscripts.com didn't work. You can try lorentz@cs.stanford.edu.
