How to change read post to unread

[Rabso]

Hi,

Let us say that I have posted new topic and it's closed topic. after some time I edited this topic. Now I want my user to read this topic again, so is there any way to change this exciting topic again to unread topic for all my members?

thanks

As far as I know an option "Mark Topic As Unread" does not exist in the moderation tools nor elsewhere. But maybe if you also add a reply to the topic, which you then (soft-) delete right away, this will make the topic show up as unread for other users.
