Hello Evolution Laser Clinic. Please have a look at wiki.openstreetmap.org/wiki/Key:contact for all your contact details. `Linkedin` would be a new key, and i think it should be `contact:linkedin` ... and there the username is enough ;-)

Hello wilda69. At way/293069534 you have tagged `html` instead of `website`, right? #typo

Or is it an import?

Hello iWowik. At
way/528271978
way/528271979
you have tagged `buiY=PL`. What is it for? Should it be `building=yes`? #newkey

You have tagged `roof:hiet` ... do you think this is okay?

Indeed, because JOSM doesn't check misspellings of keys.

sorry, i've commented also another changeset of you (changeset/52411468), because of some misspellings in the key

Und noch ein paar mehr Wegweisern, also am besten einfach nochmal alle prüfen ;-)

Hallo Lübeck. Bei den Wegweisern
