Changing the relevant text in:

bb-includes –> template-functions.php

Line 130-140 will probably do that for you:

function post_form( $h2 = ” ) {

global $page, $topic, $forum;

$add = topic_pages_add();

if ( empty($h2) && false !== $h2 ) {

if ( is_topic() )

$h2 = __(‘Reply’);

elseif ( is_forum() )

$h2 = __(‘New Topic in this Forum’);

elseif ( is_bb_tag() || is_front() )

$h2 = __(‘Add New Topic’);

}
