Design Patterns Study Group?

I found this article by the authors of "Head First Design Patterns" book. The article talks about starting a Design Patterns Study group based on the contents of the HFDP book. I am very much inspired to start a study group like that at work. It would be a great opportunity to learn more. Joshua Kerievsky has lot of information on forming a Design Pattern study group here. I might as well check that out too..
