Preview page on frontpage not working

Hi there,

I am trying to understand the preview post on the front page. I was told in an earlier ticket that you can not preview a page in the back end of the site, but only in the front end.

I have logged in the front end of the site and i see no preview page at all.

can you please point me the right direction

if you can send me a screen shot of the preview button or page to show me that it works would be great. I must be missing something as i logged in the front end and see nothing
