Treating ppl with civility is a must

That ought to go without saying, but sadly... it is rare, especially on the Internet.

I quite agree. On the net, civility and formalty is out. From my experience people has a tendency to confuse civility with formality during face to face situation. Giving ppl the technology to collaborate does not mean they can collaborate as a team From my experience, I have seen people at team meeting never seeing the big picture while focusing on their agenda.
