More about us


The goal is a publishable base without wrong information – not completeness. Anything missing or that could go deeper: report it as "idea for later". We will keep expanding after go-live.
You go through your pages and report what is factually wrong. Expect three to five minutes per page.
Please report: Anything missing, outdated or wrong – and anything visibly broken.
Please don't report: Taste, wording polish, wishes. And that forms do not arrive: that is intentional.
