Since last week I have joined two NING communities. I found Medical Education Evolution through Deirdre Bonnycastle's blog. This is a very interesting concept- radical people in medical education. But I guess it isn't as busy as I might have hoped. Still I will keep checking in and see how it develops.
Next, I was invited to join the IVIMEDS NING community. This is just in it's infancy but it will be interesting to see how it takes off too. It seems that NING is where it's at.... for now!
