you can also se the CSS option. Lets say you never want to display the title for a post. You can actually put a title in the post and then note the ID of the post. Now add a CSS Insert
HTML Code:
#post-xxxx .post-headline {display:none;}
where xxxx=the post ID. this will cause the title not to display, yet you will see the title in the backend and it will show up in the widgets - like recent posts)
