Corrections

We publish what public sources say. If the source is wrong, contact the source (links). If our copy is out of date, flag it.

How flags work: use 'Flag as out of date' next to any fact. Three flags from different readers in 30 days add a note to the fact. We never change a value because of flags alone; we change it when the source changes.

There is no contact form. This site runs without staff answering mail.
