Call time:

Just before the index page is shown.

Hook input:

function phorum_mod_foo_index($data)
{
    global $PHORUM;

    foreach ($data as $id => $item)
    {
        if (!$item['folder_flag'])
        {
            $data[$id]['description'] .= '<sbr/>Blah foo bar baz';
        }
    }

    return $data;
