Here's an example of my "tip" using the "KDE and Gnome Comparison"
URL you recently posted:

<thadlabs.com/.../KDE_and_Gnome_Comparison.pdf>

and here's the original URL:

<http://www.psychocats.net/ubuntu/kdegnome>

Note I always add the original URL as the last line in any PDFs
I create; I neglected to mention that in the original article.

> Great idea, Thad!

Glad to help, and I hope the "tip" proves useful for others, too!
