[wp-hackers] Action Hook Upon Blog/Site Creation in Multisite

Hello Mark,

I am pretty sure the action 'wpmu_new_blog' is what you are looking for. This is what the docstring for the function 'wpmu_create_blog' says:

 * This function runs when a user self-registers a new site as well
 * as when a Super Admin creates a new site. Hook to 'wpmu_new_blog'
 * for events that should affect all new sites.

The action is called with the following parameters:

do_action( 'wpmu_new_blog', $blog_id, $user_id, $domain, $path, $site_id, $meta );

I often use http://adambrown.info/p/wp_hooks to find hooks that are not in the codex.
