Privacy settings have been a big problem on other social networks (They often don't work properly or become too complicated and are misunderstood) so we have taken a very different, much simpler approach. The Profile Engine is a public social network. Everything you put on The Profile Engine (except your email address and private messages) will be public. If you are not comfortable with something being public then do not put it on The Profile Engine. Other social networks are about sharing private stuff with cliques, the Profile Engine is where you can present your public image to the world and make new friends!
