I converted the original group to page that can be liked. The page is here: https://www.facebook.com/pages/Batavia-Kart-Club/203836529655609
I used it regularly throughout the season to push out news, results, and photos but our readership is low. If you're a Facebook user, make sure you "like" the page and see if you can get others to do the same. It helps spread the word about the club.
