WordPress Multisite - global categories
I have a series of blogs that will use some, but not all, of the same posts. We have one blog where many of the posts are written, and then shared down to the other blogs, based on topic. We cannot accomplish this properly using categories, though we've thought of that.
All the blogs use the same theme, the theme changes slightly based on the blog. I would like to do something like this:
register_taxonomy( 'some_categories', array('post'), array ('hierarchical' => true, 'label' => __('Some Awesome Categories'), 'singular_label' => __('Some Awesome Category'), 'query_var' => 'some_categories') );
Is this possible? I know that WP 3.0 has a different set of tables for each blog, so this may not be possible.
