If you have been one of the lucky(?) people to be given a starter from a friend(?) then you know the amount of time and energy and resources this takes out of you. And how great it tastes. I came across this blog/site today and just had to share. (Also lets me know where to find the info again in the future.)
The comments at the end of the post are VERY long, but worth the time to read as there is a mountain of information in there! Enjoy!
