Which Ragnarok Online server do you play?

Whether it's an official server with thousands of players at a given moment or a private server owned by your neighbor's son, just post your server's name here (if it has one) or at least give us a brief explanation to it. Feel free to share your gaming experiences on individual servers. Which server you like best? Why?

I guess I'll start first. I have played in a couple of servers so far. The first server I played was the official eRO server which was probably the most crowded I have played so far. Soon, I switched to a private server named TrinityRO. Why? One of the reason was the monthly fees. Though I have a choice to buy monthly cards using "zenys" from other players, I was too afraid of scams. Not long after, I switched back to the official server eRO, same account but different character. Then, once again I switched to a private server due to the latter's monthly fees. Now, I am playing in DarkRO which houses people from different countries, US, Brazil, Japan, Philippines, etc. DarkRO is a high-rate server with custom jobs, sith, jedi (characters from Starwars) which I find amusing and fun.
