Can i use this for my multiplayer server? I want to make a adoptian home for dogs. So I figured that I would build a building around it! So may I???

I've only been in Mindcrack--I mean Minecraft about two weeks. My computer can't handle the graphics I want, and I don't know how to download yet, but this thing looks awesome! I'll admit I don't care for the war games and monster hunting, but you can't terraform or carve fantasy castles out of mountain cliffs without a few wolves around. It just ain't civilized.
