I am planning to make ranks and rights being able to buy and other financial stuff, but safety and entertainment first :) Currently I await people to make opinions and tell the world how I succeed in hosting a good server.I had a lot of people testing my plugins' security and they always came up with a new solution. Finally, I managed to set up a system that prevents griefers do their best at unbuilding.

Server is running...
CookBook with custom recipes
DropModifier with custom drops - zombies drop feather again!
Infected - the monsters cause extra effects now
MCMMO with 5x multiplier on experience gain

Server is secured by...
Four plugins to prevent grief
Rollback system to restore griefed stuff (testing it atm)

I hope you'll join and enjoy my services!

Additional Notes

Secure and fast server for anyone respecting the entertainment of other players.
