Hello,

What is the difference between unstable and testing?
Are there CD versions of either of these?  On debian.org, I notice that
there is a CD distro of the stable version--how old is this?  Is it
Sarge?  I am interested in perhaps giving Debian a try but I prefer
staying up-to-date and can't easily perform a net install over a dialup.
