The correct answers to the above solution-question are:
As "wp_get_current_user" only is available for logged in users.
<?php if(wp_get_current_user('editor')) || (wp_get_current_user('administrator') { ?>
<!-- Stuff here for editors or administrators -->
<?php } ?>
If you have a special plugin that gives multiple roles to users?
<?php if(wp_get_current_user('author','editor')) { ?>
<!-- Stuff here for author and editor -->
<?php } ?>
If you want to see if the current user is either editor or administrator
if(wp_get_current_user('administrator')) {
<!-- We identified the administrator -->
}
else {
if(wp_get_current_user('author')) {
?>
<!-- We identified the logged in user as author since we already know the
admin that is now logged in can't read this code -->
// Stuff here for authors
echo '<center>Welcome Author</center>';
?>
