Everytime I click something protected I get this message. If I would go up my farm all floors the messages would flood the chat to the point that I can no longer scroll up to see what someone wrote. It is also annoying when dealing with chests or smelting large quantities of something. I know it's possible to turn this notification off entirely but everyone would probably not want that, is there a way to turn it off for the users that doesn't want it?
Netsui is right.. I think that's the only way. xD If you make a suggestion thread, I'm sure a plugin-savvy user will be able to tell you if that would be a possible feature to be added. I personally find it useful, but I can imagine that people with a lot of protection in a small area would find it annoying.
I believe the only way to disable this on a per user basis is to manually add a negative permission for lwc.shownotices to EACH player. Just imagine how much work that would be for Andrew to have to add that to every player that thinks the notices are annoying.
