Thanks. None of these worked for me with WP 1.5 though. I see in the
source that the functions get_queried_object() and
get_queried_object_id() are defined, but I can't call them from the
plugin.

$posts[0] worked fine.

Also need to get author's ID if the requested page is author's page.
Probably get_queried_object_id() would have helped. Since it does not
work for me, I did this instead:

global $wp_query;
$user_id = $wp_query->get('author');

Is that a correct way to get author's ID?
Or is there a better one?

Thanks,
Uldis
