I dono if anyone here is signed up but I figured I would post the link if someone would like to give it a try. It is amazing what some people put out of the original picture in such a short amount of time and how horrible others can be and take forever. I did these off and on about 2 months ago and thought it was ok but gave up cause all the images and psds were takin up to much upload space.. I also liked the fact that you have to contribute 15 pictures before you can vote for other peoples work, that way you dont get teh b00nies givin bad votes or spamming shit.. anyways here is the url..
