One of the other ladies on here has had a go, but I don't know how it has turned out, and some others have success. There is a short thread on it a few pages back, I am sure.
I googled "sourdough starter", and the fifth one down has a basic beginner how-to ("how to begin"), which we have both read, and seems helpful.
Good luck. I'm not going to make sourdough, as I don't think anyone else in this little black duck's house will eat the stuff.
I make sourdough now and again. I make my starter with flour and water (just your normal homebrand white flour though jamie oliver says you "must" get organic stoneground stuff, it's worked with homebrand for me!)
I also "cheat" by adding some yeast to the bread when I'm mixing up the starter with the rest of ingredients. That way I get the sourdough flavour with an helping hand for the rise!
All the best - mine's always worked out so it's not tooo hard! Yumo!
