Well yes, don't you? I get an E-mail telling me so and so has posted a new reply to such and such thread (that I've either been reading only, or posting in), and then I must click on the link provided in order to get on the actual thread at the place of the new post. If I only read the reply post on my E-mail without going onto the Bettermost forum, I stop receiving the new replies. Which might be what I did, but I do not think so.
The person below me will tell me whether I am the only one getting E-mails notifying me of the new replies to threads I've read or posted in.
