Many of the Kontact pages are very outdated. I was looking today at KOrganizer/Embedded and wondered whether it is in fact dead, in the light of Kontac Touch?
Overall I think the KDEPIM initiative could use more help with keeping the documentation current. Yes, KOrganizer/Embedded is definately a bit old, though keeping some of the history can be useful as well. Hmm maybe sending a request for help with a list of all pages to some of the KDEPIM channels could help.
