I joined the Ning in round 1, but sadly didn't do much with it. When I revisited it this time around I was glad to see some people I had met at a workshop - so I was able to have some Friends. (Yay!)
I started a discussion topic for Teen Tech Week. Someone has responded - hopefully that will see some more action. I didn't see any groups to belong to...so maybe I'll start one. :o)
I can see using a Ning in my personal life, specifically, some of my friends from high school and I are in charge of our next high school reunion - this might come in handy for getting organized and reconnecting classmates.
