That's why if you want to make money off the server so it will pay for itself, you find some other advantages people could get instead of admin.]
Sure, you will get a lot of donations for it, but you're also going to attract a lot more younger players, and soon enough you're Havoc Gaming2.0.
What a friend of mine did was have two servers,
One a stereotypical darkrp that attracted a lot of youngn's, and a Flood.
The DarkRP let you donate for admin, and his flood made you have to be a respectable player for it.
Basically, he'd leave the DarkRP and let it keep itself alive like a self-sustained ecosystem, that helped pay for the flood. He was also making some nice dough out of it on the side as well ._.
