    CN: No, that is fine. Of course, we also needed a chapter in the manual 
(docbook). The problem is that the table from where I have this is currently 
not availeble in germany because the publisher will issue a new revision in 
"late 2005". My bookstore told me that means October to February. As soon as 
I can get it I will reactivate it, of course.

Yes, but that is a Qt4-think. Arther provides many many new things and perhaps 
KPainter2 could also be used. Depends on how fast those things progress after 
the akademy!

- Advanced:
  - Orbits
  - All but one radius
  - Mean weight
  - Oxidationstages
- Simple:
  - The rest plus Stewards table

The problem was that Kalzium only supported about five languages. It simply 
http-get'ed the data from a provider in the internet which no longer exists. 
Furthermore, it really only worked for those few languages.

Yes, sure

Sorry?

In January 2005 I asked the accessibility-folks about Kalzium, here is the 
link:

http://lists.kde.org/?l=kde-accessibility&m=110486557200822&w=2

There are several followups:

http://lists.kde.org/?l=kde-accessibility&m=110486834325180&w=2
http://lists.kde.org/?l=kde-accessibility&m=110493157203395&w=2
http://lists.kde.org/?l=kde-accessibility&m=110536616520587&w=2
http://lists.kde.org/?l=kde-accessibility&m=110536644502059&w=2

I will quote one easy-to-do-item:
"You might also wish to improve the "Keine unterschiedlichen Farben" mode 
to only use the text and base (text background) colours from the current 
colour schemes. This is important for partially sighted people who need 
to use white text an a black background, for example. The mode should 
support to show all information without the use of additional colours 
(apart from other standard colours such as highlight background and 
foreground colours). This means you would have to show the aggregate 
state as text in this case."

"Keine unterschiedlichen Farben" means the colourmode with only one colour.

Yes, but the editor only makes sense if Kalzium is able to load the data you 
create in the editor. So the writing and reading stuff is missing.
