To tag a Facebook status after posting, you need the ability to edit the status update. If you included an image in the original post, an edit option appears, so you can retroactively tag the status update; status updates without a photo are not editable. If you didn’t include an image in the original post, you can delete the post and create a new one, but you’ll lose all the comments on the first post. A better alternative is to simply add a comment that tags the person. Writer Bio
