Hi Tony,
We have been having email issues with the forum, and we believe they have now been fixed. You should receive all email notifications moving forward. If you are subscribed to a particular thread, or forum section, you will receive those emails when a new post is published.
We apologize for the delay with the email issue, but just with everything, the forum is going to get better little by little.
On the McMurray thread, double check to see if you are subscribed to the General Discussion section.
