that is no problem however check one thing on your domain registrar whether the setting of accessing your domain with and without "www" is selected or not.
Mate don't worry about it, it means absoloutely nothing. If you search Forum Promotion in google, we will also be without the www. (as we have a 301 redirect set to the www.) as with my own site, it doesn't mean anything and is nothing to worry about :great:
You can change it by placing a redirect from http:// to http://www. and then when google re-indexes your site for changes, updates etc. it'll show as www. instead of no www. 😉
Also @ DeadandWalking your signature image is so hard to see, maybe you should change the font to black 😉
