Can I make sourdough bread in a breadmaker?

[CSLewis]

I have a Panasonic bread-maker, and make 'normal' bread all the time, but would love to know if there is a relatively easy method of making sourdough in it too. And does anyone know anything about a 'No-Knead 'bread-making method I've seen mentioned in passing?

TIA!

The no knead thing is called a Grant Loaf. Tastes quite nice if a bit heavy. Always found it a bit wet and best toasted. Quick though, and quite acceptable.
