@Frans S
Let me say something about your comment - it really upset me. I learned to use some validation tools in JOSM that prevent update data with non-orthogonal buildings. NONE of my buildings had wrong shape. A comment like yours just convinces me to stop mapping forever. Sorry, but that's how it is. Please, write such comments really only to people who make these beginner mistakes. I'm definitely not a beginner!!! Thanks @anthaas for sticking up for me.
Sincerely yours, Thea Satneshamah.
