Recently we have turned back on the ability to subscribe/unsubscribe from threads when logged into the forum. You will notice a new link that says "Subscribe to this thread" or "Unsubscribe from this thread" at the top right corner of each thread post. Remember, this is an email subscript
ion, which means you will get notification emails
whenever someone replies to the thread since the last time you viewed it. In order to receive these emails, your email address in your profile must be current and up to date.
You can still subscribe to a thread when posting a reply post and you can manage all your email notifications/subscript
ions from the My Profile > Edit Email Subscript
ions tab. One thing to keep in mind is to limit the number of threads you subscribe to, otherwise the list will become very long and essentially unmanageable.
I hope this change makes it easier to follow your favorite threads!
