Finally - I heard my bread sing!!

I managed to bake a small but rather tasty loaf of white SD bread this weekend using nothing but starter.  When I pulled it out of the oven it looked a little mis-shapen, but as it started to cool I could hear the crust crackle!!  I was soooo excited, I've never had that experience before.  The crumb was moist, tender and had a lot of smallish holes (probably because I kneaded it too much) and it is pretty tasty.  I now have 3 starters in the refrigerator - 2 "wet" and 1 firm WW and I've successfully used the firm starter in Pan Bigio from The Italian Baker - really impressed "La Famiglia" at our last family dinner.  This web site has really inspired me to accomplish wonderful things when it comes to baking bread - thank you all for your advice, wisdom, etc.!!
