It has been suggested multiple times and after years of just not getting around to it I have finally setup sudo on the community server and, unless a problem turns up, that will be the way forward for doing superuser tasks.
I have sent emails to everyone that I have setup new accounts for on the server and given sudo rights. If you have not received an email and think you should have, let me know.
