"The Sleepover Club", although an Aussie series, was a focal point of our formative year. It was about five young girls who started a sleepover club in order to stay friends forever. Fun fact: Frankie Sandford, played by Caitlin Stasey, went on to join the cast of "Neighbours" after the show ended in 2008.
