What are some good forums for talking about editing photos in Photoshop or GIMP? Where do you talk about such things?
EDIT: Other than here, of course.
Completely agree with jrista, but assuming you meant "other than this cool place", I like dgrin's "Finishing School" subforum.
Well, I would recommend this site first. ;) Discussing the editing and post-processing of photos is one of the primary purposes of this site, and as a strong support here, I can't help but promote it. It may be rather slim right now, but given the overall success of StackExchange sites, I do not doubt that this site can become one of, if not the, top resource on the Internet for photography and photographic editing questions.
