I don't find 'community' particularly useful
Larry Gorenflo - email@example.com - I don't find 'community' particularly useful in this context, in that it already appears as a technical term in the ecology and socioeconomic work that I generally do (and that a lot of users of SEDAC, I suspect, also generally do). That stated, I think the secondary headers work well in that they serve to guide users into the site from other angles. I think in general it is a good part of your beta site. Sorry, but again I don't have any real organizational recommendations or useful comments. Well, except that I suppose one approach might be at some point (maybe elsewhere) to provide some map that allows users to point and click, at least to get listings of datasets or even sub-pages within CIESIN (though in truth, though I find these geographic interfaces often useful, I think for what you have here it would be overkill as there are several ways to get to the information one generally would want.
