One of the projects we were working on before we lost the business internet connection was a Minecraft Server. It runs Minecraft paid for, not that hacked sshit out there so you've got to have a legit minecraft account to get on.

It is a complete b***h to administrate. Keeping all the mods up to date and griefing is a full time job in itself. Plus, GIR only has 4GB of ram which makes it limited to probably no more than six people online at the same time.
Also, it would interfere with any webhosting GIR might do in the future.
I could bring it back up on the temporary while GIR is down as a webserver if enough people showed interest in RAWR having a minecraft server.
To have it be permanent, it would need to make enough money to pay for itself, idk, at least $20 a month. Is there a way to make money with a Minecraft server other than donations? Can a adsense account be bolted to it?
