I don't seem to be getting any emails when someone posts in a thread that I'm "watching". As far as I can tell, my account is set up properly to do that.
I I don't remember if it has been going on for awhile as I don't post that frequently. I just noticed that I did not get emails in a thread that posted in today, although I did get an email for this thread. I don't know if it's because I originated this thread but was just someone who replied in the other one. I did check my spam folder and did not find anything there.
