bind key "say /moneyme"
Instructions:
1. Replace "key" with any other key you want - make it one you will remember
2. Copy and paste the bind with your key (i.e. bind / "say /moneyme") and place it in your console
Note: If your config.cfg file is set to read only you will have to rebind it every single time you get out of the game or exec your config.cfg file.
3. When you need money, just simply press the little key.
Easy enough?
