Theme Horse

Ok, so you need an example…

I have breadcrumbs enabled, and my posts categorised. If i view one of the posts the breadcrumb is like this:

Home > Category > Post Title

If i click the “Category” link in the above breadcrumb, I’m taken to a page that has all my posts on it. I want to edit this page. I also want to add this page to a menu.

My issue is I cant find it anywhere to edit.
