1) Same as my Planet Minecraft username, Ailedroc. 2) I'm sorta good at redstone, and pistons, and I can take user skins and make the heads into houses. 3) I'm having trouble finding a good, fun server. 4) Griefers are horrible people. They completely destroy everyone's Minecraft experience, and I wish to do the opposite.
Also, creepers drop music discs when killed by a skeleton's arrow, in case you didn't know. (Shoot a creeper with arrows 4 times, get it following you, then get a skeleton to follow you. The skeleton will try to shoot you, but he'll shoot the creeper, who will die, and drop a record.)
