Keep starter in fridge with no need to feed. Stir any liquid back from time to time if necessary, but no need to constantly feed it. Feed it with the excess of any new starters being made for baking. This is similar to the levain method
Some people have suggested feeding a starter and putting it in the fridge and only feeding it any left overs from new starters being made.
I left 1/4 cup starter in the fridge and made a new one out of 2 tablespoons and about 1/2 cup whole wheat flour and 1/2 cup water.
