Me neither. I may spin up an instance to have a nos around but I assume the general Admin business is a bit like the administration of a web forum in which there’s a backend with relevant tools and the settings, presumably a way to upgrade from there. I’m pretty familiar with that kind of thing over the years.
Access to the actual server is likely to be different again but if there is a web admin panel then getting a few people signed up to that should help at least resolve the current issues.
