This and ActionScript 3.0 Design Patterns are already in my library, it's just the applying of this into real world applications that i now need to master.

If we pooled our bucks we might be able to attract the attention of the gurus....or as we used to pronounce it in Missouri - ga roos'
Actually, AS3 Design Patterns would make for a killer study guide.
