I have discovered the power of Google Docs for sharing. Forgive me for my enthusiasm, I'm not so quick as some of you.
What a brilliant tool. I've created several documents already to share with colleagues, and we've all had fun adding comments and using the chat facility.
Above all though, I think this will be really productive. An easy way for us to share a combined piece of work, adding to it as we have thoughts or ideas. Fab stuff.
