Last updated over five years ago, several hyperlink targets have since
become broken, most notably the link where new contributors to KDE
projects are directed to place a request with the KDE Sysadmin Team for
a kdemail.net alias if they desire one.

The target URIs of the above-mentioned link and other meta-links to
general documentation and generic KDE web resources (icons, disclaimers,
etc.) are brought current to the correct resource locations.

Additionally, the primary content of the page was expanded and
copyedited where it seemed both appropriate and needed to make the page
more useful and informative to its target audience: new contributors.
