I added a post with instructions on how to enable the email notifications for subscribed threads/posts as it is disabled by default as far as I know.
How to receive email notification for subscribed boards/threads.
There is an option in your profile settings regarding subscribed thread notifications.
1. Use the guide in the previous post to
get to your profile options page.
2. Find the setting that says "
Post and Board Notifications:"
3. In its right field that there is a dropdown with the following label "
Notify me of new Notifications by e-mail?", set to "
Yes" if you would like to receive an email for thread update notifications.
4. (Optional) you can also find all the threads you have subscribed to and remove your subscriptions by browsing to "
User CP" from the main menu, then selecting the "
Posts" and clicking on "
View my Notifications" link.
