Announce post in a single fixed category
I have created a separate category where i want only announced post to appear. I want to do this in such a way that i don't change the main category of the post. So if post "abcdef" belongs to category "xyz". It can also belong to category "123" where it is announced without losing its initial "abcdef" category.
Please anyone know how i can achieve this? I'm just a beginner in web programming with full html and css knowledge
