How do I upload new Themes to my WordPress blog?

Themes are located in the following path on your web server:

/httpdocs/wordpress/wp-content/themes/

You can access this directory on your web server using an FTP program like SmartFTP, FileZilla, CuteFTP, or WS_FTP.

We have preinstalled several themes on all sites.

To learn more about themes, check out Using Themes in the WordPress Docs.
