I think tribe should have some kind of system or thing that would let people know your "real" rather then someone who just posted a picture of their friend or who ever. Have a Verification Photo, like as an "option" a person doesn't really need to do it, but it lets people know your really the person in the photo", have an instruction saying you need to put your "Tribe name" on a paper or what ever with your face clearly visible. Example; if I were to do it I would put my name on my paper saying my name "Ted" and some where on the paper I'd put "Tribe.net" or the place to find your page, then it would be something like "www.tribe.net/tatchak" Well if we were to do that it would be "optional" and you'd be able to put that certain photo on your main page.. Like when you add them "optional things like the text, blog, lists, ext. Well that was just my thought...
