Using technology to network

I've been mulling over how we can "refresh" the BAOT student local groups.....by using our computers a bit more to keep in touch! There are so many different ways to connect online now...discussion forums, facebook, bebo etc. The student local group network aims to connect students with each other... and me. However, organising meetings and then updating me on the issues discussed....can, I'm sure, be a bit dull and time consuming. If we can utilise our electronic networks a bit more...maybe the network will be come a bit more "dynamic"? Suggestions, as ever, are welcome.
