I've been a member of quite a few photography and digital editing forums since going digital a couple of years ago. I have found what I think is the best by far. You can join for free at http://www.outdooreyes.com Navigate to the forum to get a taste of what's available.
The first few topics are technical in nature, and the many other topics are for posting your images and comparing notes.
Everyone there is VERY helpful, whether you are a pro or a rank amatuer. You can ask any question, no matter how simplistic, and you'll get good advice without that 'Holier Than Thou' attitude you get at many sites. This applies to photo techniques as well as to Photoshop help.
Although I've been into photography since the 70's, my images have improved noticeably in just a few months of comparing images, methods, and equipment with these folks. C'mon over and teach a little, learn a lot.
