As I have been reading in this article here

http://wpmututorials.com/category/basics/

there should be cretaed some tables at the installation. Those tables are

wp_1_categories !! missing

wp_1_comments

wp_1_link2cat !! missing

wp_1_links

wp_1_options

wp_1_post2cat !! missing

wp_1_postmeta

wp_1_posts

wp_1_terms

wp_1_term_relationships

wp_1_term_taxonomy

wp_blogs

wp_blog_versions

wp_registration_log

wp_signups

wp_site

wp_sitecategories

wp_sitemeta

wp_usermeta

wp_users

As you see I'm missing three of these tables at install. Should they be there or did I missunderstood the articles?
