WordPress MU

Is this the best way of getting this information? It seems the user data isn't available in the global space anywhere I can see by default, but I could be wrong about that.

$user = wp_get_current_user();
$addr = get_blogaddress_by_id($user->primary_blog);

It's only two lines, can't go wrong with that... though if there's a function that does this already, why duplicate right?

Same circus, new clowns:

$user = wp_get_current_user();
$details = get_active_blog_for_user( $user->ID );
$addr = $details->siteurl;

$details includes the following:

stdClass Object
(
    [blog_id] => 63
    [site_id] => 1
    [domain] => domain.tld
    [path] => /
    [registered] => 2006-05-10 00:56:29
    [last_updated] => 2009-09-03 02:52:54
    [public] => 1
    [archived] => 0
    [mature] => 0
    [spam] => 0
    [deleted] => 0
    [lang_id] => 0
    [blogname] => Pingo Lingo
    [siteurl] => http://domain.site.tld
    [post_count] => 1222
)

$details->blogname being quite useful. get_active_blog_for_user has the bonus effect of double checking that the current user is a member of at least the dashboard blog and eventually spits out their primary_blog as that if they have no other blog.

Thanks dsader. :) Learning as I go.
