How do I get postbit plugins to work in PMs?

[Claygp]

Well .. I wasn't really asking for help with code .. I'm asking how to get postbit plugins to work in PMs. Is there a hook location i'm not seeing here? Whats the trick?

Anyways .. if you really want to see the plugin code .. here's one of them (in postbit_display_start - works perfectly in the forums, but NOT in PMs):

$collections_query = "select count('x') collectionscount from collections where user_id = $post[userid]";

$collections_result = $this->registry->db->query_read($collections_query);

$collections_row = $this->registry->db->fetch_array($collections_result);

$collections = $collections_row[collectionscount];

.. and in the postbit template:

<if condition="($collections > 0)"><a href="/collections.php?user=$post[userid]"><img src="/gfx/mycollection.gif" width="78" height="16" border="0"></a></if>

.. in PMs .. the image is showing up for EVERYONE.
