Cool, I've always wanted a worm farm! Might have to keep an eye on this thread and get one started As far as I know, you can buy actual worm farm set ups? They're in layers, and certain things go in each layer - like you're putting all your scraps in the top layer - that's your compost, and it breaks down to the next layer (where I think the worms are in dirt?), and then it breaks down to another layer that you can use to fertilise the garden. I'm not totally sure about that though - someone with a better idea will pop in hopefully, or I might go Googling
