Shayne was fortunate to be around helping out a team of open source developers working on Mambo when a large portion of them decided to all get up and leave to start something new, Joomla. 
Shayne since then has built a profitable business around it called Cloudum, a Perth/Western Australian, based Joomla solutions provider. He gives us all a little history lesson on Joomla as well as a awesome security tip in regards to keeping your website secure.
