Sounds like a very complicated project, @hukadan! I'm assuming this is a long-running process?
If you guys host my nodebb, can I customise my theme / upload my own theme?
Hey @Giorgio-Chiodi -- the hosted service does not provide administrators with the ability to directly access their server/instance, which is part of how we can maintain stability on our platform.
You can grant us access to a theme you created (if it is on npm), and we can install it for you, but we cannot ensure compatibility with them
