To redirect all traffic on a site from www.raybdbomb.com to raybdbomb.com (or vice versa, as required), thanks to no-www.org:

In your .htaccess file
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.domain\.com$ [NC]
RewriteRule ^(.*)$ http://domain.com/$1 [R=301,L]

Where instead of domain.com, you put your domain.
