Nice Idea, but how do you will practice such a collection sharing???
I collected photos from longhaired girls since 1994 and now I have more than 50.000 pictures of "normal" longhair and more then 15.000 pictures and videos from nudity/porn longhaired girls and 1000 pictures of own longhaired models-
Do you know, how much time I was for these collection in the internet and how much money it costs?
And how do you will manage for instance 3 or 4 of such big collections- a lot of pictures are than double and triple and all users have the own management system for the filesaving!!!
Sorry for my bad english (I am a German) but I hope you understand my arguments!
