I seem to be spending a fair bit of time explaining what the error messages and warnings in Weathermap mean, lately. It has got me thinking that I might just add a little code to the end of each message, that says something like [WM0220], and have a list of those messages here, each with a few paragraphs of explanation.
I thought that the current messages were pretty clear, but maybe I'm wrong... certainly there are plenty of people searching on google for the text of those messages, too.
