Years ago I voted for creation of dsb Wiki on IncubatorWiki, and meta even before the Incubator started. And I happened to have the privilage to be one of the first to edit it, and to make some first lay out for the main page (although the edits seems to be deleted now, or they are left on incubatorwiki)
I am mostly active on Czech and english Wikipedia.
I would love to help, but I fear I would introducy inaccuracy. I can understand written sorbian language, but I cannot write it.
I may help with categisation of existing articles, by taking info from infoboxes...
