harrygno,
I'm sure someone in London could help you get over these initial teething problems quite easily.
There is the GLLUG (Greater London Linux Users Group) which has a very good mailing list
see
http://lists.gllug.org.uk/pipermail/gllug/
for the archives.

Use [email protected] to email a question or beg for help. - is it O.K. to write this email address?
They also have fairly regular meetings where I'm sure you could find someone to help.

There is also a "free" book that Knowing Knoppix that you might find useful.

If you fancy a trip to Southend, SoSlug meets every Thursday night.
See http://www.soslug.org/

I'm sure somebody there would be able to show you how to get going with Knoppix.
Regards,
Mark
