Long time on this... I think I found a viable way to offer a convenient data access solution.
I am currently evaluating it. If you feel inspired to test it, connect via FTP to
User and Password: The same credentials you are using on the site skygems-observatories.com (not the forum credentials!).
I would be very interested in the feedback. We tested it also via SFTP but had a performance drop which made it unusable. We could also activate WebDav if anyone prefers that (also in parallel). I will try to make some benchmark with the WebDav before, though 🙂
