Are you trying to build features for your server using redstone but find yourself limited by the lack of wireless signal? Then you'll be glad to find out that this simple script lets you do just that.

Options:
DefaultBlock: (block) - Defaults to cyan glazed terracotta, is the type of block that uses signals.
Check: (number) - Defaults to 4, is the time delay between checks.
Permission: (permission name) - Defaults to RSDeluxe, name of the permission for certain parts of the script.
