Specifically, I am looking to describe a person whose only purpose is to help others, not caring about what happens to  himself or herself (physically or otherwise), though without actively seeking pain.


Question: Could not add 'LoginLogout' link using BAW login logout plugin
Answer: Have you tried printing your custom link just by checking if user is logged in? you can do this using bult in wp functions

&lt;?php
if ( is_user_logged_in() ) {
    echo '&lt;a href="'.wp_logout_url( get_permalink() ).'" title="Logout" class="hunderline"&gt;Logout&lt;/a&gt;';
} else {
    echo '&lt;a href="'.wp_login_url( get_permalink() ).'" title="Login" class="hunderline"&gt;Login&lt;/a&gt;';
}
