Home page settings
There are two categories in this blog: Uncategorized and Hidden.
We set our option (using a plugin) to exclude the “hidden” one from here, so only posts in the Uncategorized will show up on the main page.
The posts from the Hidden category can be accessed only by clicking on the cat name in the top menu and going to the category archive page.
