Dear Siqsuruq,
by default .LRN will also install the news package, which will be mounted at the /news/ path of your website. You could put your news there and unauthenticated users will be able to access that page and see them (readonly, of course).
If you want the /news/ page to be the starting page of your website, you can set the IndexRedirect parameter of your main subsite to "/news/". To do so, go to the subsite administration (/admin/ path of your website) and click on "Parameters". In the page you will find the IndexRedirect parameter.
Hope this helps. We could give you further tips in case.
Ciao
Antonio
