I want to blog about a broad topic, but at the same time, focus on two or three narrower aspects of that topic too.
I have several domains, one for the broad topic and one for each of the narrow subtopics, and I want to redirect each domain the appropriate place in my new blog(s)
When I post on one of the subtopics, I want the post to appear in the correct subtopic area and also in the broad topic area.
When I asked about this on the WordPress.com forums, I was advised to come over here and ask about setting up multiple sites.
Can I nest sub-sites that each have their own visual theme and set of posts but also have a main "parent" site that contains its own posts and look but also echoes all of the sub (child) sites?
