Have you found any? Please share links to sites you have found useful.
I have not found much yet, but it could be that I don't know where to look or what search terms would be most useful on Google and other search sites. Here are a couple of things I found, though.
A good definition and discussion of third culture people from a site called International Schools Services.
http://www.iss.edu/pages/kids.htmlAnother good definition from the US Government's Department of State.
http://www.state.gov/m/dghr/flo/c21995.htmThere was the Global Nomads Virtual Village, a Web 1.0 site that aimed at something similar to what I hope this site will become, and it is certainly dedicated to the same audience, but I can't find anything that has been updated there since July 2006.
