Adventure map Starterkit

You may use this as a "starter" or spawn for your adventure maps. When someone joins they will immediatly hit the wires and send a signal to your command blocks. This is useful for setting a spawn because you can tp a player there, it can also be useful for setting up important server rules and settings. Credit would be nice but not needed. Also a diamond would be much appreciated. Thanks!

Additional Notes

The spawn is on a flat world which is 1 dirt block deep, 10 stone, and finally 1 bedrock. This spawn may be copy and pasted into other maps but please do not reproduce just the spawn as your work.
