BuddyPress.org

To get my blog comments to link to their Buddypress Member profiles, I had to create a custom comment function (explained here: https://codex.wordpress.org/Template_Tags/wp_list_comments ) and then create a link around the avatar. In the link I used <?php echo bp_core_get_userlink( $comment->user_id, false, true ) ?> as the href value.
