Basically, it commercialises the AoD idea. I'll have to take a better look at it tomorrow when it isn't 1AM, and try work out how I can do this (I'm thinking along the lines of "warrants", and I have an idea for the betting one too, relating to returning items.).

So yeah, Dave, if you want to install a betting system to an AoD, you now know where to come to. And to the others, if you want somewhere to advertise your store, you can use my Arenas for a price, and to the winners, I'll try add some profits for winning if I can think of a way.
