On-line collaboration tools

Have spent a little time this week looking for o­n-line collaboration tools to use with the various committees that I am o­n. It is hard to find good cheap (ie free) tools. It is even harder persuading everyone o­n a group to change to o­n-line working. However, this way of doing things is here to stay. Those who don't learn to use new ways of communicating will just end up out of the loop, I think. Those with IT skills and digital ways of thinking and processing information will go far.
