Upload local wordpress site to live free wordpress
===

I am using wordpress for the first time, I have created a news/blog website called trimline news. I have created the site locally using MAMP, (modifying the twenty eleven theme). <br />
What I want to is upload the website I have made to a free wordpress site, so trimlinenews.wordpress.com, I have been looking for tutorials online how to do this but I can only find ones that require you to have your own server and domain.

Can anyone please help me out, or point me in the direction for help with this.

Thanks in advance, Tom
