Not sure where to put this inquiry. I check the box to be notified of replies to threads but get no notification that I can see.
How does one use this feature?
I think that if you check the box you'll get an email to the the email address that you have in your profile contact information if someone posts to the thread. Check your profile to see if your email address is correct. I used it once or twice and it worked for me. I checked it for this reply to see if it still works.
