What we could add to get more players on the server is multiple worlds. What I mean is we could have 1 world for creative projects, 1 world for Survival (no pvp) and another one for smp survival (with pvp) . This would bring more players because there would be a world for everyone depending on what you like to do in minecraft. In the world with pvp we could add a faction system. And for the creative world, I know we already have classic but let's face it, classic is dead now and doesnt offer half the things SMP does for creative builds.
Also I have noticed that the banner that we use on voting sites is outdated because it has the old spawn on it so I think ti should be updated.
I know that the multiple worlds idea is very hard to do and time consuming but in the end it would be profitable because more players = more donators and more donators = better server, more slots etc etc.
EDIT : Please move this to smp suggestion tyvm.
thank you
