After testing today (I unsubscribed from this forum and this thread to make sure it really unsubscribes) I offer my solution.
I've been advocating for a LONG time for auto-subscription, especially for the OP, so we know they actually see the replies we work on. If they have to check it off to make that happen, we're back where we were on the old forums. So...I'm prepared to uncheck (we have more incentive to uncheck than they do to check), and I limit the number of e-mails by this method, which yields me only the notices I want:
FIRST: I don’t subscribe to anything I check regularly (daily or more) anyway…which is to say, Europe Multi, France, Italy, Spain, US Multi, New York, New Jersey, Tips/Tools General, Air Travel, Currency, Cameras.
SECOND: I do subscribe to New Jersey, Maine, Scandinavia, Portugal, Pennsylvania and Washington DC, where I keep an eye on things and might miss new posts because there’s less posting.
THIRD: Anywhere else, I only subscribe to individual threads that catch my attention.
Another poster also made the suggestion of having the forum e-mails go to a separate e-mail account so you only see them when you go there to check them....
