What is "photosig"

PhotoSIG was a community website for photographers, online from December, 2001 until December, 2014 that allowed members to critique one another's work in order to improve their photography skills. Critiques were highly valued, which differentiated PhotoSIG from photo sharing communities or gallery websites. It was free to join the community, although a few features required a paid membership, such as autonotifications of comments and a higher number of photo submissions.
