How to use: Place two signs: One sign that has the text [Warp] on the first line with anything on the rest of the sign. The second sign with the text: [Teleport] X Y Z of the warp sign.
When a player right clicks the teleport sign it teleports them to the designated warp sign if one exists at those coordinates.
