Yes I think more people will join and it will definitely bring in more donations.
I don't know if you want to check it out Kyle, but I just finished a spawn server yesterday, it is differnt then most spawn servers. It is pretty much like old Runescape before all the new items came out, but the new items are still in the game. It has a Pkp shop which is the only way to get some of the items, and for the Donator items, you need to kill monsters to get the items, so you still have to put some effort into it. Just a thought, if you want to use it.
