Thing 10 is now in the bag. As I was looking for networks, it felt as though Ning is more specific or at least the "blog pages" look different and have more options, at least to me it did than a regular blog. I hope this made sense.
When names of groups were put into the search box, the groups popped up and then when I asked to join, the paper work came then my birthdate, etc. One negative thing otherwise my experience was o.k. I unsuccessfully looked for my high school back in Chicago and could not find it but then I found a successful martial artist web page and ultimately signed on to a network about the city of Chicago and how to make it a more complete scene.
