Click on the "Edit" link at the bottom right. This will take you to the text window where you can delete some or all of the message. This is time limited - you only have so many hours to do this before it becomes locked. If you still want the message deleted all you have to do is contact a Moderator.

If you delete the text and change the subject line to "Please Delete This Post" we'll quickly see it and take action. Once we get replies, we'd prefer not to have to delete a post but it is still possible.
As Ernesto suggests, a note to the modertors will also take care of the issue.
