The server doesn't need new admins, showing that there are
any active staff in general will do. I haven't played a lot I only know of Cinathair and Hugh Jass being moderators. However, just moderator presence does show activity.
What really turns people away from a server are servers that do not update in general or servers that are only friendly to Donators.
If you REALLY wish to help the server stay "alive" while the programmer is away continue making suggestions, reporting bugs just keeping the forums alive is a good effort.
In no way am I being rude by posting any of this just my own personal opinion
