The German OSM Blog just kicked off its 2nd weekly task (Wochenaufgabe). The goal is to encourage mappers to tag a certain POIs during that period.

The first task was to tag bicycle tube vending machines. Over the next two weeks (community wanted a bit more time) we want to improve the coverage of electric charging stations.

In created a Wiki page to keep track of the tasks and make it easier for non-German mappers to take part:
