God Help Me I cant find a solution! WP Subdomains

Sup fellas n Gals,

Im trying to have some sub domains using one word press installation, if my site is something dot com I want aaa.something.com to be subdomain with one content page to become the main page for it, all the links surrounding the content container will be directed to , now......theres a plugin called "WP subdomains" which is able to make a category use aaa.something.com as the main page, it states its able to do it with pages but Ive had no success with it, I read online a bit and the bottom line is that the plugin is just not working as it should.

Anyone got a solution, would be GREATLY appreciated.

WP multi-site feature is your answer I believe http://www.wpbeginner.com/wp-tutorials/how-to-enable-multi-site-option-in-wordpress-3-0/
