Things worth writing about
A chart looks wrong
The most useful message this project can get. Every chart names its source and links to it - send the chart title and what you think is off, and it will be checked against the source. A chart that is wrong gets taken out of circulation the same day.
Research and data requests
The aggregated drawings are the point of this project. If you want to use them, say what for and what shape you need.
