Posting in the forums gets you money - the longer the post the more money you get.
Do you mean something like Kingdoms/Moba Lisa (by Ren, False? and Iskall the sweedish potato)? I could go for that!
Mob Arena is a fantastic way of earning money. If you do it in teams, you could earn thousands each time you play, and you can play as much as you want!
Posting in the forums also adds to the community spirit. Don't think of the forums as an obligation to play on the server, think of it as something like a community of fellow minecrafters (or mincerafters).
Moba Lisa would work really well on the server, as so many of us come to the server from Rendog's channel and would therefore know a fair bit about kingdoms/moba lisa.
Moba Lisa could get off the ground faster with more people (btw it is known as Kingdoms AND Moba Lisa)
If you really want to get a lot of money, just play mob arena. But the money is just a small part of the server.
But yes, I support you with this.
