An authorized user clicked a button and the article did not appear to him again?
She would just be hiding for a certain user.
Algorithm:
1. A person visits the site
2. Authorized
3. See all the news on the site
4. Click on the "hide" button for a particular article. More article with this ID is not shown to him.
!!! For other users, the article is visible until they also hide it.
Help to implement this. I am sure a couple of lines of code are needed there. I can not navigate.
