If the Introduction to the Personal Web Site Starter Kit white paper wasn't enough for you -- we have a new one -- Extending the Personal Web Site Starter Kit -- a great way to learn how to customize the kit -- more than just an overview.
These types of papers are in production for the Club Site Starter Kit and the TimeTracker Starter Kit -- so expect those soon! Let me know what you think.
PS -- get the SK's here: http://lab.msdn.microsoft.com/express/vwd/starterkit/default.aspx
Download the files, make sure they are xxx.vsi (club.vsi for instance) and that you have Beta 2 installed. Then double click the .vsi file and VS should launch the Content Installer and away you go.
