This is a true curiosity which caused some good laughter today. A colleague showed me his check marks in Firefox today. They were upside down and have been so for a long time. He does not have a clue why they are not the usual way. It does not matter on which web site he wants to place check marks. Be it Moodle, be it Doodle (as in the screenshot), they are always upside down. Should we now call them “hut marks”?
