Hello @jaqueap
Please see the advice in this prior Q&A. It would apply for most public Galaxy servers, not just https://usegalaxy.org.
If you still need to contact the administrators of a different public Galaxy server, contact information is usually on the home page of the server itself or noted in their directory listing here: Galaxy Platform Directory: Servers, Clouds, and Deployable Resources - Galaxy Community Hub
Thanks!
