Pardon my ignorance if what I'm asking already exists in DarkRP, but, as someone running the commands you provide, can you tell how much they already have?
If not, the perhaps a command to tell you (I dunno, 'getmoney'?)
Again, my ignorance of DarkRP is strong (I have enough real world life..I don't want to role play one)
Also, I stronly encourage you to make your own addon folder/path.
I cringe for the support issues that pop up when people add files directly to our folder paths.
