ok, so I know how to filter variables (and am documenting for the codex), but I cannto figure the syntax for an array.

As an example (and apologies for long code – but in this case hope you’ll let me off!)

function bbp_list_forums( $args = '' ) {

	// Define used variables
	$output = $sub_forums = $topic_count = $reply_count = $counts = '';
	$i = 0;
	$count = array();

	// Parse arguments against default values
	$r = bbp_parse_args( $args, array(
		'before'            => '<ul class="bbp-forums-list">',
		'after'             => '</ul>',
		'link_before'       => '<li class="bbp-forum">',
		'link_after'        => '</li>',
		'count_before'      => ' (',
		'count_after'       => ')',
		'count_sep'         => ', ',
		'separator'         => ', ',
		'forum_id'          => '',
		'show_topic_count'  => true,
		'show_reply_count'  => true,
	), 'list_forums' );

	// Loop through forums and create a list
	$sub_forums = bbp_forum_get_subforums( $r['forum_id'] );
	if ( !empty( $sub_forums ) ) {

		// Total count (for separator)
		$total_subs = count( $sub_forums );
		foreach ( $sub_forums as $sub_forum ) {
			$i++; // Separator count

			// Get forum details
			$count     = array();
			$show_sep  = $total_subs > $i ? $r['separator'] : '';
			$permalink = bbp_get_forum_permalink( $sub_forum->ID );
			$title     = bbp_get_forum_title( $sub_forum->ID );

			// Show topic count
			if ( !empty( $r['show_topic_count'] ) && !bbp_is_forum_category( $sub_forum->ID ) ) {
				$count['topic'] = bbp_get_forum_topic_count( $sub_forum->ID );
			}

			// Show reply count
			if ( !empty( $r['show_reply_count'] ) && !bbp_is_forum_category( $sub_forum->ID ) ) {
				$count['reply'] = bbp_get_forum_reply_count( $sub_forum->ID );
			}

			// Counts to show
			if ( !empty( $count ) ) {
				$counts = $r['count_before'] . implode( $r['count_sep'], $count ) . $r['count_after'];
			}

			// Build this sub forums link
			$output .= $r['link_before'] . '<a href="' . esc_url( $permalink ) . '" class="bbp-forum-link">' . $title . $counts . '</a>' . $show_sep . $r['link_after'];
		}

		// Output the list
		echo apply_filters( 'bbp_list_forums', $r['before'] . $output . $r['after'], $r );
	}
}

If I wanted to turn off the topic and reply counts, I could use a filter which would look something like

function hide_forum_counts () {
$r['show_topic_count'] = false ;
$r['show_reply_count'] = false ;
$r['separator']  = ' ';
return $r ;
}
add_filter('bbp_list_forums','hide_forum_counts') ;

Stephen, JJJ or other bbp genius – can you post the answer, I have tried everything to prevent needing to copy all the original function, but have failed

This is what you want for the above:

function hide_forum_counts() {
        $args['show_topic_count'] = false;
        $args['show_reply_count'] = false;
        $args['separator']        = ' '; 
        return $args;
}
add_filter('bbp_before_list_forums_parse_args', 'hide_forum_counts' );

A full example of all the bbp_list_forums arguments to use either in a custom function or a plugin https://gist.github.com/ntwb/3797945
