Yes, i am a member of NAPP..
i joined for the main purpose of learning Photoshop...
The online tutorials are great, but one thing i really felt was needed is a little structure.
there are in-depth courses for every aspect of the tool, but they are like a library..
it isn't like say - a Lynda.com's module, where Chris Orwig structures the entire session into different modules, starting from the basics like layers, selections, masking before going in-depth and into other topics.
THAT is missing from NAPP or that's how i felt...
There is one session of basics of photoshop for photographers which gives a basic outline of what's available & then plenty of courses on each of them...
I really wanted to see if there was something out there that i couldn't/wouldn't get online from free resources, like youtube for example which has tons & tons of videos some excellent, some not so good..
if you want my honest opinion, save your money, view as many tutorials as you can from the free resources.
it will do just fine..
