Do any of you receive notifications when someone replies to a thread for which you've posted a reply? I've never received any, and my preferences are set to send notifications.
Not by default, no. If that was the default, some of the regulars here would be inundated with emails.
You'll need to bookmark the thread by clicking the star at the top of the thread just above the "POST A REPLY" button. That is how you indicate that you want to "follow" a thread and receive notifications for it.
I hope that helps. Please let me know.
