We are running version 3.5.1 on Minecraft 1.7.10. We always have keep inventory on. PVP is not allowed, nor is greifing. There are gyms but a staff must be on (which is almost always) to compete in a gym battle. Unique items are given to those who win gym battles including Pokémon eggs! :D We are not pay to win and we won't be accepting donations either, we are completely free to play!
