Thank you for your feedback, I guess you’re right: it’s not a real account. I still don’t know how to solve this. On my end I am by now completely on my own, which means it’s no longer viable to run an association on this basis. I cannot even hold a meeting, just with myself (and Julia and Nikuska who would take part but not share responsibilities).
As far as I’m concerned its best to do a full backup and then give up on this project in the current form. No idea what comes next.
