I'm trying to set up a weblog that has a front page with a set of announcements, etc that are of interest to a general population, then (what appear to be) a set of individual blogs on topics of interest to only a subset of users. The individual blogs are accessible through links on the front page. Here's the catch: the search function has to search the entire set of blogs, and the sidebar on each blog has to be identical.
Rather than actually make separate blogs, I thought I would use categories to sort incoming entries into the sub-blogs, with a separate index template for each sub-blog. The thing is, each sub-blog should have several categories of its own. This leads to the question: can I have sub-categories that live "underneath" higher-level categories?
For instance:
category blog1 has subcategories A, B, C
category blog2 has subcategories D, E, F
Thanks,
