bbPress.org

the bbcodes notice i think you can turn that off in the plugin your using, i think its gd bbpress tools.

you can remove the unrestricted html notice with some CSS if you want its only displayed to Admins/Keymasters only, so its not that big of a deal.

you can use this PHP code to remove the notice above the topics/forums

add_filter( 'bbp_get_single_forum_description', 'ja_return_blank' );
add_filter( 'bbp_get_single_topic_description', 'ja_return_blank' );
function ja_return_blank() {
    return '';
}
