Which template is for thread subscription?
showthread template has the link for add / remove thread subscription ...
<li class="subscription_{$add_remove_subscription}"><a href="usercp2.php?action={$add_remove_subscription}subscription&tid={$tid}&my_post_key={$mybb->post_code}">{$add_remove_subscription_text}</a></li>
No, I am talking about that one, which displays in the new reply
^ Post Templates --> post_subscription_method template
