No... lol there is no www for that website. WWW refers to World Wide Web. Your website is hosted via a Sub-Domain, which sets your website's "name" in place of the www, and uses your host's name after your site's name, then .com, .net, etc.
So, if you register your website as a Sub-Domain (something.x10hosting.com) it WILL NOT have www.
BUT, if you're going to purchase an actual domain, and use x10 as your webhost, your website WILL have WWW infront of the domain that you purchase. Example:
www.something.com "Something" would be the name of your website, www is telling the browser that it's worldly viewable, and .com is telling your browser that it's a "Commercial" website.
Got it now? Lol
EDIT: Did you purchase that domain? nexteam.com? You must do this via another website, because x10 doesn't offer domain registeration. Might I recommend signing up for a free account
HERE and then purchasing a domain for $6/year?
