I would also appreciate it if someone could keep an eye on the consistency of the expressions used (e.g., telling me if I once again used X-Windows instead of The X Window System). If someone volunteers to write an unwritten chapter or to contribute changes/additional material, I would place his/her photo on my desktop with a golden border :-).
Although this book is nice for the beginner, we need more in-depth documentation for the specific KDE applications. If you would like to contribute, please contact me immediately.
