I used to manage incoming customer mail for a company, and I think an easy
way to start a letter-writing program is as follows:
Everyone buy a few cheap postcards & 20c stamps & leave them by your
computer.
When someone identifies a problem like the tortilla/oat fiber one, please
address the group with SUBJECT: LETTER REQUEST and enclose info and address
of company.
Whomever reads the request will grab a postcard, jot down something like "Why
did you add Oat Flour to your corn tortillas? I am on a gluten-free diet and
can no longer purchase them" with a return address sticker. We should
really see results that way.
Length of letter is not important. Number of letters received is important.
