Kay,
I'm sorry it's taken me so long to answer! I was out of town on vacation.

When you post a message on the forum, there is a box to check that says "If you'd like e-mail notification of responses, please check this box:".

If you don't check that box, you won't get the email. My guess is, you didn't check the box. Probably when you posted before you had checked that box.

In fact, before I posted your message I forgot to notice whether you had checked that box on this forum.

But anyway, I think that's the only difference, so just remember to check the box when you post.
