Subject: Re: [TSSP] Welcome to the project
hi Paul,
I am not running a UNIX system at the moment(win 2000) ,but I intend to
install a linux system at some point in the near future. I am very busy with
my outside catering business at the moment, but this will drop in about 3 or
4 weeks, then I should have more time. I have very little experience of UNIX
so it will be a steep learning curve. From my experience of uncle bills
software it sounds worth the effort. I have a friend with a first from
Cambridge in maths and stats so I can run stuff past him if needed.
cheers
bob golding
