finding and inputting wordpress templates for your blog

There are many sites where you can find free templates for your blog
http://www.wpthemesfree.com/ is a great one (google wordpress themes and you will get a lot of options)
Once you find a template you like, and download it’s zip file, unzip it.
FTP the entire unzipped folder into the site files.. but in a very specific directory.
It’s within the blog folder, then WP_content, then themes (you’ll see two folders here already, classic and default.)
Once it's uploaded, you will see it in the PRESENTATION area of your blog.
You simply choose the one in there you want, and view. You can change the look of your blog anytime without compromising the content.
