I usually use the "Show new replies to your posts" to get updates on the forum when I want to go fast. This is usually useful. But I happen to have posted in topics I do not necessarily want updates on (for example, "caption the avatar above you"). I have actually quite a few of these and I would like to clear them from my list. I can press "Mark as read", but it's only effective until another reply is posted.
Is there a way to delete a topic from there permanently?
