Nice work with /sc, hope you make more plugins.
The plugin works very well and it is very lite.

What's the point of proffing your ownership if that's just skript? Also what's the point of joing stuff chat? If someone is in stuff he automatically should see all the stuff messages. Simple 4-5 lines with "loop all players, if loop player has permssion "bla bla bla".

By the way, you uploaded wrong file, it's Gems.sk
