I must be overlooking this in my profile, but I don't see a way to opt out of email notification of responses to a topic that I've posted. Surely this can be done. How do I do that? Thanks

Nevermind. I tried the link in the emails that connects to the notification preferences. The wording is a little vague. I initially thought that selection only applies to the particular thread that it is linked with, but maybe it works for all response notifications. I'm guessing that it does.
