Good point about reSt, I've send an email to Waldmann-EDV.

Also send an email to roundup-users to announce our move
and the current state and a question about the default markup.

== Default markup language?

Note that our software can do Creole markup (by default),
many instances of moinmoin we have at Intevation use this as default format 
now, because it is simple and can be used elsewhere,
like roundup. :) See https://wikibeta.roundup-tracker.org/Markup

Would anybody mind a switch to creole as default?
(For a page this can be changed by the #format directive, so no page
must be 
migrated.)
