General Thoughts

AJJ - Adrian mentioned metadata and search engine optimization. This is an important issue - Google has a document about this: [Google SEO Guide]

ARR - Here are some preliminary ideas for extra metadata to put on the site:

<META name="description" content="Portal for small angle scattering - information and resources">

<META name="keywords" content="SAS, SAXS, SANS, reflection, facilities, beam lines, instruments, programs, software, conferences, jobs, news">
