Great to hear the project hasn't died. Will keep watching out for calls for entry. Looking forward to put in my bit, even if it may not be selected for final publication... that is all part of the game.
Which makes me think, would it be an idea to create a special (temporary?) APUG gallery of all photos that "Didn't make it"?... A bit similar to National Geographics last page "Photo that didn't make it" in the NG magazine? If so, it might be best to publish it sometime (3 months, half a year?) after the book has been published, when the first excitement and frustration has died down... to avoid overly heated discussion of "Why hasn't this photo been included?!"
