After using the site a bit, I am finding one challenge. When I go to comment or critique a photo from another photographer, I am able to hit the 'post comment' button. But when the area pops up to type in, there is no longer the image to look at. It does make it a challenge to give a good solid critique if I can't see the image while I am typing? Sometimes I may get on a tangent and then forget to mention something.
