Ralf, John, 
so what do you think about the Waldmann-EDV offer overall?


== Preserving contributed code files
Another detail: It is probably easier to extend Moinmoin to display
attached files as code nicely, (maybe even with syntax highlighting)
than doing this will Allura's SF wiki engine. Moinmoin can be extended
by plugins and the options specialised-Moinmoin-Hosting or using a hoster
would allow us to run MoinMoin plugins.
