Select one of the entries in the center Course panel from the main menu and start browsing. Communication via e-mail with some researchers around the world about their current investigations made me eagerly anticipate new results. The more I learned the more easy it became to put off writing a final draft because my curiosity would lead me on yet another line of inquiry.
