Hi Ralf, where did you comment other than here? The HOT project manager in this case is this chap https://tasks.hotosm.org/users/surveyor_jr. Project managers can be contacted via the HOT tasking manager under the specific project (https://tasks.hotosm.org/projects/16836#questionsAndComments). There is also a Slack channel for HOT OSM which will get the attention of the higher ups and maybe get better results. I sometimes find that these HOT projects get put out by relatively inexperienced OSM mappers as some sort of study project but then they seem to do little to supervise what happens afterwards
