This is wonderful! Just pulled it into JOSM and working great. One tweak that would make it even more useful - at the moment the decimal figure after the year maxes out at 10 for December. So it takes a bit of quick reasoning to estimate the month. Do you think there is any way of adjusting that so that the figure after the date matches the month, e.g. 2023.11 would represent – ‘some point in November 2023’?

@map_papi look through the OSMCal events and anything with ‘Missing Maps’ in its name will be a good event to join and get started with Missing Maps. For example the next London Missing Maps event is a fully online event with lots of training (https://osmcal.org/event/2726/). If you represent an organization that is interested in becoming a member of Missing Maps feel free to get in touch with me on sam.colchester@hotosm.org

Nice piece of guidance, this is surely a time-saver and puts ‘common errors’ or ‘things to look out for’ in a relatively prominent place. I wonder though how you deal with this when there are a lot of posts in the question and comments section of a project.

Sometimes there are several pages of posts and the mapper may struggle to understand which is being referred to. Would having a direct hyperlink to an individual post in the questions and comments section help with that?

Great post! These are things that I’ve been thinking about in an unstructured way for the last five years - but you’ve put these same thoughts into words brilliantly. Sounds like the Missing Maps London community and the Missing Maps Prague community have a lot in common :)

This particularly resonates, well written:

“The core team … work hard to be replaceable because that’s what the community needs. They only succeed if the community works without them; the community can not depend on one person.”
