This is a drupal feature to allow a large group of friends to coordinate their gaming activity. The original intent is board games, but LAN parties and console games could just as easily be organized using this feature module. Create a list of games, then start adding events and locations for the events. Once that is all setup create tables for games to be played on at the events so that people can sign-up. The signup module allows you to limit the number of people who can sign up for each game so you can be sure that games don't get offered too largely.
The Sermon project is a way to provide a sermon structure for your Drupal church website. It includes a number of ways to explore your churches sermons and allows your shut-ins and traveling attenders to stay in touch with the sermons.
Your sermons may have images, notes and sermon series tracked on them. You may choose not to use these options and they may simply not be used when creating the them for your website or marked as exclude on the Content Type display page.
