One a day, I tried a server called ProjectX. It's really great! They have good mods and a two great owners. The server is slowly decreasing in member because people are looking at stupid servers that mods everyone for no reason.
This is a PVP server.
Anyway, the server has two mods and two owners and is not whitelisted. It has MCMMO, donations (with BuyCraft), factions and many more! I donated to this server. My username is acerspyro and the server's IP is:
mc.prxcraft.com
