Sometimes it's all too easy to stick to our old habits when using MS Office and we never quite appreciate some of the cool new stuff there, well a bright spark in our team recently pointed out the session sharing feature in Onenote 2003 SP1.
It allows you to share out a page and allows multiple editors to join in- it's just great way to collaborate especially after the initial euphoria of following our innate instincts and treating it as a graffiti/doodle pad (opps, http://news.bbc.co.uk/1/hi/uk_politics/4220473.stm :-) ).
I now use whenever I can as it helps keep everyone on the same page (so to speak) and great when your colleagues are spread far and wide!!
Anyway, to start a shared session click on "Tools -> Shared Session -> Start Shared Session" and for people to join in then they click "Tools -> Shared Session -> Join Shared Session".
PS. You need to have a publicly accessible IP address for the machine hosting the session either on your intranet or internet and it works over port 2302. So for internet based collab you'll likely need a socket proxy such as the ISA Client loaded on the inside of a firewall and on a home network then you'll need to port forward 2303 to the machine hosting the shared session.
PPS. and dont forget this needs Office 2003 SP1:-)
