ET under Linux

EDIT: Added "About ET & TS", "About ET & Vent" will follow!

This is my first tutorial, so constructive criticism is appreciated.
NOTE: Iam using ubuntu linux 7.04, so this tutorial should quite match to Debian, Kubuntu and the other ubuntu versions. About other linux distros i dont have a clue to be honest.

First of all, when i tired to get ET running under linux, i was far away from knowing everything about it.
Thats why i want to thank some people who helped me alot first:
