I'm trying to set up a WPMU test environment with 5-6K blogs, lots of posts comments, users etc.
Browsing trough the WP's functions, I picked up wp_insert_post, wp_insert_comment, create_empty_blog(), and wp_insert_user().
So basically I would run a big for loop in which I create random blogs, get their ID, switch to each of them and insert posts with random content.
Is this really this easy as it looks? :) Or I'm missing something here?
