Forum How can I edit the forum subscriptions

[محروم.كوم]

How do I, as a user/admin, Subscribe to a forum, so I receive notifications of all messages created within that forum.
Currently in UserCP, under "Subscribed threads" I only have the options;
"List Subscriptions" - can only edit thread subscriptions here
"Edit Folders"

How do I get the option,
"edit Forum" - so I can automatically subscribe to forum.

Also is there a way as an admin to automatically subscribe users to forums.
Urgent, much thanks in advance. __DEFINE_LIKE_SHARE__
