Triple P

Something like this:

<div class="loginpopup">
<?php if ( is_user_logged_in() ) { ?>
// welcome message goes here
<?php } else { ?>
<a href="/wp-login.php" class="simplemodal-login">Log In</a> <strong>|</strong>
<a href="/wp-login.php?action=register" class="simplemodal-register">Register</a>
<?php } ?>
</div>

Put this in your css:

#footer #subscribe-rss a {
display:none;
}

It won’t disable the rss on your site though.

To create secondary loops, make a new instance of WP_Query with the desired parameters:

// Create a new instance
$second_query = new WP_Query( 'tag=foo' );

// The Loop
while( $second_query->have_posts() ) : $second_query->the_post();
	echo '<li>';
	the_title();
	echo '</li>';
endwhile;

wp_reset_postdata();

Check the IDs and classes with Firebug or the like, and hide with css:

function hide_that_stuff() {
    if('YOURPOSTTYPE' == get_post_type())
  echo '<style type="text/css">
    #favorite-actions {display:none;}
    </style>';
}
add_action('admin_head', 'hide_that_stuff');

correct, I assumed you had admin access 🙂

It’s probably hidden, but it should still be accessible via e.g. http://mysite.com/wp-admin/theme-editor.php

Make a new list item like this:

<li id="signup" class="widget-container">
	//your stuff
</li>

and position it right below:

<ul class="xoxo">

Should work!
