This seems pretty cool, but sometimes a plugin may not update as fast as our server does so it will cause some problem for the people that need wool while no one is currently selling.
What? The lift signs in the server wool shop would be a good idea, and it would be as fast as the server, and it would be faster actually then going up the stairs. Also the wool shop has nothing to do with people selling wool, so wool will always be selling.
What nradke is saying is, in the future when Minecraft moves to a new version, the plugin may not update, thus the lift would break and part of the wool store would be completely unavailable.
Hmm, seems logically to do it. Just when the plugin gets out of date change it to ladders. Or maybe .....LADDERS
