I have created a small challenge via MapRoulette to fix something that is bothering me: The usage of http only url’s. The effort would give me the chance also to review non-existing urls as well. The OSM database is pretty old and some update with the correct location could be necessary!
If you want to create a challenge for your own country the overpass query i used for Bulgaria is this:
[out:json][timeout:299];
(
area["ISO3166-1"="BG"]->.a;
nwr["website"~"."]["website"!~"^https?:\/\/.*"](area.a);
nwr["contact:website"~"."]["contact:website"!~"^https?:\/\/.*"](area.a);
);
out body geom qt;
He is my challenge which now it seems complete :) Yay!
