“For some reason, this forum never notified me of any replies to my post. I apologize for not seeing these until now.”
There’s been a change how this is handled. If you used to receive email notifications but don’t anymore, you need to go to “My Account” (while you are in the forums, it’s the third item in the options at the top of every page) and then press “Request Email Notification of New Postings To This Message Board”. Note that you have to do this for each of the different boards that you enter from the main SierraGamers.com site.
