Mikey,
Did you give any starter away at the meeting?
Another thing that people can do once they get a starter that they like, is to freeze it. Mix the starter with some flour until it is very dry mix. Let it set at room temperature for a day to let the yeast/lacto desiccate. Place in refrigerator for a day and then the freezer.
Once you decide to use it again, use Mikey's 1 part water to 1 part flour to bring it back to life.
By the way, your starter is a pet, so you need to feed it once a week
Love this stuff - thanks Mikey!
