The Wochenaufgabe @osmwa was the Weekly Task of the German OSM Blog (Category:Wochenaufgabe). Every 1-2 weeks they presented a new task to encourage users to map in the following days.

Since 2020, there is the Schwerpunkt der Woche ("focus of the week") with a similar concept.

Everybody can suggest these tasks. Usually they are small POIs like a charging station or certain type of vending machine.
