PluginWiki anyone? This is the official WordPress Plugin Competition Repository of information and documentation. Please be considerate, this wiki will be actively monitored.
Expect the PluginBlog to follow soon (in a day or so). In keeping with the philosophy of sharing, I encourage each and every participant to register in the PluginBlog and post often. They should keep their audience (the WordPress Public) well informed of their plugin goals, provide lots of links back to their blogs and generally blog about their plugins and the competition.
