After "Default Thread Subscription Mode:" there is a drop down box with several options. I had chosen "Instant email notification" It's still that way. I don't see anything to "check" under that category.
However, I did get another email notifying me of YOUR post, so it seems to be working for this thread. I don't have any idea why it isn't (wasn't) working in the other thread. The other thread (about he icon) is the first I'd made in here for months, and the lack of email notifications was what prompted THIS thread. Hopefully it was just a fluke.
Thanks for your reply.
