ning thing

I had already joined ning, although it was awhile ago and i don't really remember why. for some reason, i also have a second account and joined the network "Library 2.0" at http://library20.ning.com/, but again haven't been very active. I did comment on 2 forums today though, and applied to join the ALA network, but I'm not sure if you have to be an ALA member to join. Guess I'll see.
