Communication, communication, communication

Arguably one of the most important things in a project is communication.

In a project I started all briefing for new participants with the words
"I have three things that are the most important things in this project. They are communication. Communication. And communication." I then wrote this on the black board and let it stay there for the rest of the meeting.

I still believe communication is one of the most important things and if anyone has any input about how to communicate better - please drop me a line.

What I am primarly looking for is
- how to aid communication, how to make it naturally
- how to communicate lots of information in little time
- how to store communicated information
- how to search and retrieve communicated information
