Solved:
Subscribing to threads:
PROFILE> FORUM PROFILE
MODIFY PROFILE> NOTIFICATIONS
THE BOARD USES "NOTIFICATIONS" as a way to subscribe to thread, called "Current Topic Notifications." ""Current Topic Notifications" = both Notifications of posts is enabled and a list is generated for each of those threads you post to or start (your subscriptions).
TWO OPTIONS TO SUBSCRIBE TO THREADS:
1. You have to check "notify" on each thread you post in or create before in order to generate the "subscribed" threads list, again, called "Current Topic Notifications."
2. In the NOTIFICATIONS settings, choose: " Turn notification on when you post or reply to a topic." You are automatically 'subscribed' to each thread you either post in or start.
#2 will automatically allow you to get notifications when a reply is posted, and below that there will be a list of your "Current Topic Notifications" which is the same thing as a SUBSCRIBED thread. If you do not enable "notifications" you will not be notified when a reply is posted, nor will a list of your subscribed threads show up. (IMO, this should be enabled automatically.)
You can find your "Current Topic Notifications" (Subscribed) threads on the same page, just scroll down. This page is where it all comes together:
HOME>PROFILE>MODIFY PROFILE (drop down list on hover)>NOTIFICATIONS
All information to notify (subscribe) and a list of your subscribed/notified threads will be there.
