I made a little progress on a forums index listing

then the Forums page sub-nav tabs would look like this:

the only action that will add something to the forums directory component subnav is <?php do_action( 'bp_forums_directory_group_types' ) ?> which forces use of the ajax bp_has_forum_topics( bp_ajax_querystring( 'forums' ) )

so i decided to hook on <?php do_action( 'bp_directory_forums_content' ) ?> or do_action( 'bp_after_directory_forums_list' ) both below the topic listings. the first action will display the forum index on all subnav ajax tabs (all topics, my topics, and tabs) the later will only display on the forums directory page until a subnav tab is clicked.
