I added you on skype and sent you a message. This is so everyone can give their input on this as well. Have an incentive system where if you donate say $5 you get the starter pack which consists of something like half a stack of food, iron armor, and iron tools. Or a Technology starter pack for BC stuff and one for IC2 stuff. They could be whatever price you choose and consist of basic machines and engines/generators to power them. You could also make an advanced one that is something like $25 and consists of enchanting table, bookcases, diamond armor, diamond tools, and bottles of enchanting. And a final thing you could sell just plain bottle o' enchanting for whatever price you choose.
That could work however if i cant pay the bill for the server in about 2 days. My server gets taken apart and everything is removed
