When the player places down the TC, Send the player a message advising them that the Tool Cupboard has been locked for their convenience and the Code is XXXX and if it has been loaded with materials etc, I find new players dont understand howto change the code or use it very well.

sure i can add something like that 

that would be awesome

i have completely rewritten the plugin and added a few extra features including the messages you asked for . im going to publish it just before force wipe as it requires you to set it up again from scratch and delete the data folder . if you would like to try it before then you can message me on discord if you like and i can send it to you there sapnu puas#3696
