[K12OSN] users not logging into my thin client environment

LTSP in the classroom also takes a shift in how a teacher restricts or
monitors what goes on in their lab.  One of the beauties of the LTSP
environment is that if every student has an individual log in, they
can change their background, their home pages, add icons to the
desktop, choose their windows manager (KDE, Gnome, xfce if you've
chosen to install them).  Not having to restrict this and monitor
technology actually frees an instructor up to focus on teaching
technology rather than spend time monitoring it.  If a kid messes up
their Gnome configuration, delete the Gnome configuration file in
their home folder and they're fixed.

It took me a little while to adjust to the different way of thinking,
but it was very freeing to me and my students.

That's my opinion anyway.
