Facebook - the Internet's premier social networking site - has an "Event" function in which events like parties, sporting events, debates, etc. can be posted in the Facebook system, to which people can be invited to and note their attendance.
I've gone and created an event listing for next week's home opener. If you have a Facebook account, RSVP to the event and invite your friends. Get the word out about the game.
Here's the link:
