You can find this function in bb-includes/functions.php

function bb_add_topic_tags( $topic_id, $tags ) {

global $bbdb;



$tags = trim( $tags );

$words = explode(',', $tags);



if ( !is_array( $words ) )

return false;



$tag_ids = array();

foreach ( $words as $tag )

if ( $_tag = bb_add_topic_tag( $topic_id, $tag ) )

$tag_ids[] = $_tag;

return $tag_ids;

}

The explode() function is where the logic is happening… you’ll have to test to see if it screws up anything else, cause I’ve not tried it.
