In this Do it with Drupal presentation Karen Stevenson has cloned Meetup.com in Drupal and called it Groupal. Hear how Karen incorporated Organic Groups with events, locations, rsvps, photo galleries, and activity streams, all stitched together with Panels and Views. In the process of building this out we had to analyze which of several alternative modules to use for location, signup, activity stream, photo gallery and other functionality. Karen will discuss why we picked the modules we did and will note others that might work as well or better in other situations.
