NAPP is many things to many people. I love getting the magazine each month. I also use the web site to access member's only discounts on tons of tools and equipment. They have an absolutely huge education area. Got a question, send them a note in their Member Services area. Lightroom users can find a wealth of tips, tricks, and training help as well. From time savings to discounts, you'll more than make up for the cost of your annual membership.
I'm planning getting my next two purchases, an Apple workstation and Alien Skin's Exposure 2, from the NAPP member discount center.
Make joining NAPP one of your New Year's resolutions. Tell them that you heard about them from Jim Hoerricks on the Forensic Photoshop blog.
