As this clearly is leading nowhere anymore I freeze this blog.
Too many things broke down over the years (and wordpress updates) and too little was there to say.
I also work on starting a new, themed, blog on another domain. Announcing that blog will be the last post here.
In the meantime I migrated to a new theme, that actually looks decent and deactivated the old, broken translation plugin.
This is why you see all bilingual content double (German + English).
