First unsolved problem: how do I make my location visible on my user page?
Fragment of a discussion from User talk:Ronja Addams-Moring
The location is only stored in a template, which lets us do things like this. If you want to add map yourself, you can do it for example like this {{#ask:[[User:{{PAGENAME}}]]|?Coordinates|width=300|height=300|format=openlayers}}, which will stay in sync if you update your coords with the form.
