There's really not that much to it, I always try to keep things simple
Basically...
- Users can buy items through the 'Buy Stuff' section
- They use their bought items via the 'Inventory' section
- They can 'trade' an item (put it in the Trade Centre for a price they specify, and someone else can buy it off them)
- And other stuff (not much)
I still haven't had time to write up some proper documentation, but it's getting there (see the
Wiki for the current documentation)
