Kontact is not found in the Knoppix 5.1 CD It's actually located on another version of Knoppix 3.9. I was wondering if I can copy it from one CD and install it in the other... it's just an idea.

or Kontact can also be downloaded from the origiinal website as a tarball... I'm not sure what to do with it after the downloaded.

I could not open the downloaded file... I thought the file would open like a zip file...
