Less than 20 replies and already 3 complaints, clearly the server owner messed up when he chose the admins. I believe if he re-did the admin group, it would get populated. But it's not like he will, so he can enjoy his empty server, alone.
There is definitely not a problem with admins on this server. The admins do a good job, and there's there's not usually one on. People don't play on it because it's newer than the other servers and a lot of people don't know about it. If a group doesn't start playing in an empty server, no one joins. The groups are always on the ATS/Hospitaller server, therefore, people go there.
