Thank you for your reply!
I’m not sure if what I’m doing is correct, but here’s a better description.
I have a Q&A site and I used Instant Q&A premium theme from themeforest. It uses WP to have questions and answers. I want to have a seperate blog as well. So, I created a new page and inserted the code from the Page of Posts codex. Now, I want to modify that code so that it shows only the category “Blog” on that page. Then, I will exclude “Blog” from the front page and the category list, and create a seperate tab in the header to reach my “Blog”.
I believe that is what the “Page of Posts” coding if for. I want to know where in the “Page of Posts” coding in need to insert “Blog” in order to show only the “Blog” category.
My site is here.
Thanks again!
