How to delete my message on forum

Helo i know how to edit but how can i delete my message (i need to delete on message)

You can delete your *replies* to a thread.
Only admin can delete a "thread-starter" (initial post in a thread)
You can reply to your post to say: "admin, please delete this thread..."
Since a reply is a "new" post, it is likely to be seen by someone who can act in your request.
