The idea is a proper course on GEO, not a glossary behind a sign-up form. We haven't built it, and there is no half-finished version worth showing you. GEO is a new enough word that most of what is written about it is guesswork; if we are going to teach it, we would like to have measured it first. The docs are where the real material is today.
