[wp-hackers] Get query variables and tags

[DD32]

What i would do:

$tag = get_query_var('tag');
//Might need to convert 'MyTag' into a TermID here.. not sure
$objects = get_objects_in_term('post_tag', $tag)
$posts = get_posts( array('post_in' => $objects) );

Or something similar.... You'll have to check the get_objects
function.. and WP_Query for the correct usage of post_in..
