On my website, i need to post a new article 2 or 3 times every months in the tipical section "News".
Now, I have 3 different pages with 15 articles each page.
I need that every time i post a new article, the oldest post of pag. 1 move automatically to pag 2 and the oldest of pag 2 move to pag 3.
How can i do it?
