I write in reply to your notice of changing from “subscribers” to “sustainers”. I feel it is a bit risky. But on the other hand it seems a bold step which might call forth greater support than you ever dreamt of.
I can’t remember what my subscription is but I would, at least, wish to retain it at its present level. Maybe, if it is possible I would consider slightly increasing my subscription, though I am not weathy being an 80-year-old pensioner.
Best wishes for your new venture!
