Oh, excuse me for bad description.
I want to make some post page (with comments) displayed to visitor when he opens my site’s index page, for example: mysite.com/
When I say “post page”, I mean page of full post (ex. mysite.com/?p=102) with comments (created in “Posts”), but not a page created in “Pages” section of WP.
Also, It won’t be static forever, it’s like a feature
Thank you for you help.
