As Jo Ann said, if it's embedded on your site, readers will find it at your-site.com/blog (or whatever you call it).
Shameless promo, but it's an example of an embedded full-page theme with comments allowed:

Notice the address?

On Jo Ann's site, she's using it for news and events. Some others use it to display photos or artwork.
The really nice thing is that no one needs to have access to your site or FTP info, so there's no chance of anything getting messed up

Hi there, I know this is separate to the current subject. But how did you get your website theme to span the whole page with the main website body centered to the middle?
this is my website made with VSD http://www.footballmanagermad.com as you can see my navigation bar and banner are limited to the page width. How do you get it so that these expand across the whole screen regardless of screen size? whilst keeping the website main body to a restricted middle area that remains centered.
Thank you
Matt
