http://www.buildagreenhome.com/ is not a free hosted WordPress.COM blog and you cannot get support for it here. We provide support only for free hosted WordPress.com blogs like http://clarkhillwoods.com/ here.
WordPress>ORG and WordPress>Com are completely separate and have separate logins. If you don't have a username account at WordPress.ORG click http://wordpress.org/support/ and register one on the top right hand corner of the page that opens, so you can post to the support forums there and receive advice from WordPress.ORG bloggers.
I signed up through WordPress to have this website hosted through DreamHost so it wouldn't say WordPress in the URL anymore.
After you hire a web host and set up your WordPress.ORG install, install a theme and plugins see here please:
If you’ve registered your domain through WordPress.com and now want it to point to a blog or website hosted elsewhere then you can do this by updating the nameservers.
To move you content from your WordPress.com blog into the WordPress.org install see here > http://en.support.wordpress.com/export/
