You know those little headers that say "Authored by at 10:00"? So far, I haven't had a Drupal set up in which they were actually wanted. I googled it and the best suggestions I had come up with were to add display:none; to the info's class in a custom CSS file. Not bad, but it seems a little clunky. Someone on StackOverflow almost had it right when they suggested making changes to the settings of a specific theme. Of course, not every theme (including the ones I have been using) have this option. It turns out, though, that the settings can be set globally by going to Administer -> Site Building -> Themes, then clicking the "Configure" tab. Simply uncheck whichever node types you want to disable the author information for under "Display post information on".
