How do I set up and npc so when you click use on it theu open up and you can pick an item off it like your choice of a stack of food ?

Most likely with another plugin.  I know that GUIShop and possibly ServerRewards will work with it, surely others.

Yeah I couldn't figure out how to make them two work together.

If you have time I would also like to see this. Like maybe a trade? Give a blacksmith npc say 10 HQ and he returns someting he crafted with a custom skin.  Would just make the game more interactive for players.  Also is there a way to make a player just speak directly to the player without saying it outload in chat.  I have setup a quest line using numerous npcs but they give out codes to doors etc when you use them.  Anyway to make them tell the person directly without it broadcasting to everyone?  thanks for the updates too.  I see that you put the music stuff back in and have a band command.  Glad to see someone is working on that.  Would like to see where you coul dhave many band members play the same song at once when clicked on.  maybe even a mini file where they could play several songs?

Is there a way to setup a NPC as a vendor where players can turn in their diesel fuel for something else?
