I'm not sure if this is even possible. Ι'm trying to build a site using thematic. It's gonna be separated in two distinctive parts. A portfolio and a blog. I want portfolio projects to solely appear as a unique category and not mess with the blog post categories. I don't want projects to appear anywhere else but to their dedicated pages, never on next previous posts, blog page etc. The problem is that many of the projects are set in multiple categories e.g. post under both projects category and portraits. Should the post be only under one category and what that means for search engines?
I'm not sure i'm made it clear?!
Unfortunately the site is tested locally.
