What is the correct way to do this (after 3.0)? Also, I didn't find this function mentioned in the code at http://core.trac.wordpress.org/browser/trunk/wp-includes/deprecated.php Ancawonka 19:57, 11 August 2010 (UTC)

This is not correct (any more?). The function returns an array containing four values (blog_id, domain, path, postcount)...

And I guess that a link to the list_all plugin could be useful for some people..!? (http://wpmudev.org/project/List-All)
