The other day I noticed that KDE UserBase has a new look.
For those of you unfamiliar with KDE, it is a free and open source desktop environment, development platform, and application suite, primarily for Linux and other Unix-like operating systems. Portions of KDE are also available for Mac OS X and Windows.
KDE UserBase is a wiki containing helpful documentation for KDE users. While KDE TechBase is for more technical information, primarily for developers, the UserBase is designed to be simple and straightforward, even for beginners.
