This mod allows you to setup payable (although that part is also optional) signs on your world/server, there are more than one sign "type" and more may be added in the future.
Example use cases:
setup a sign at your server spawn giving free cookies or other proviant to new players
setup a sign at an inn/bar serving up to 2 times soup every 12 hours
setup a sign that runs a command to give the player a region (e.g. in worldguard) for a set price and duration and make it run another command after the duration to take the region away
WARNING! All commands added into a sign via this mod (by default) get executed by the server! Meaning usually any command will pass, similar as if an operator executed it.
Dependencies:FCL & FSMM (Money/Currency providing mod, with configurable items!)
