I think it's time to change the server... This isn't eufrag anymore and that's not necessarily bad. Eufrag died years ago and we saw it die. I don't think anyone actually misses Eufrag itself, we just miss the community, which was an amazing community and very active. Who misses the lack of admins, new maps, new plugins, new features, events...? I simply don't. Fortunately, quite a lot of people tried to bring the community back with csfrag and actually managed to keep it working.
I missed this last year completely; I have no idea about what happened, but the servers are dead, so dead... It's obvious that many people just quit playing this game and it's normal. But there's something wrong here... No one else comes. So maybe it's the right time to make a push and keep changing how things are done for the sake of what's left of it, at least.
I would start by figuring out how to manage the new server as a community in the very first place. Make new people stay, make the old ones stay... Old eufrag was a dieing, unmaintained server, with Calig alone with barely any admin powers, but people still kept playing there.
Possibly half of what I said is wrong, so that is my one cent... Hope it helps.
PS:
- Don't ever remove xoom's admin
- Count me in if you need more people to mute all russian kids.
