The August German Linux Magazin starts with a three page introduction into OpenGroupware.org as a lead article and features a Knoppix CD which boots up with a fully usable test installation of OGo ! Just plug the CD into the computer, boot from it and you can start trying OpenGroupware.org.
There is definitely no faster way to get a running OGo installation.
Note that the article contains some small bugs, for example the DocShare module for OGo and the ZideStore native client integration server are actually part of the OpenSource contribution !

An Linux Magazin article comparing various commercial Groupware solutions for Linux. OpenGroupware.org (SKYRiX) does quite well :-) Note that the test was made with SKYRiX 4.0 and we have improved quite a lot in the meantime ! (eg ZideStore was not available back then)

A linklist of various groupware servers. OpenGroupware.org is already listed !
