Fun Server Ideas...

This topic is for people who can think of some fun ideas for a popular server... I currently run a 24/7 PvP server with 1000 slots and no lag. My most recent idea involves 2 simple plugins... Citizens 2 and Sentry for Citizens 2. I have used the sentry's customization to make boss fights all around my spawn for any challenge the player wants to face. Even though my regular players like it, something doesn't make a lot of people join. My player rate is usually at a 5-10 and here's not much fun with just a little bit of players. You can submit your ideas here, and/or join my server: derpcraft.mineocity.com
