The National Association of Photoshop Professionals (NAPP) is about as good as it gets for digital photography and anything related to Photoshop, Illustrator, Dreamweaver, Flash, InDesign, and other similar Adobe products.  They put on Photoshop World, produce Photoshop User TV, and publish two magazines and a ton (well, just slightly under a ton) of training materials like books and DVDs. Definitely worth looking into.  Schnitzer figures it’s NAPP who’s responsible for most of the good stuff that he teaches.
