In my personal opinion, the server should have more game masters, particularly from different time zones, what this will do is, uphold the upkeep of support with technical issues as there should always be a GM alert, being able to monitor chats and support concerns. Considering it's not a job position and being a GM doesn't cost wages it's probably a pretty good idea for the betterment of the server and it's players.
Successful candidates should undergo a written interview or something similar that determines the persons level of commitment, passion, and interpersonal skills in trouble shooting and problem solving.
Just a thought.
