I am missing the original post, however I can answer a question about
starter storage.

It has been reported, and that knowledge exists in the oral tradition
that sourdough starter does not freeze well. That may be true for some
starters, but it certainly is not true for all.

Carl's 1847 Oregon Trail Sourdough Starter will freeze quite well with
no apparent change from the original after being revived from frozen
storage.

The best way to store or archive (at least Carl's) is to dry the starter
and freeze the dry start in a air tight freezer container.

Carl's starter has been dried and frozen and later revived. That
revived culture was dried again and sent to several competent culture
keepers for comparison with their culture of Carl's starter. There was
no obvious difference between the revived culture and that which had
been continuously propagated.

I have frozen dry starter from 2004. This subject was rampant sometime
that year. The 2004 culture still revives very well to culture that is
indistinguishable from current culture.
