Let's go ahead and learn how to download and install a WordPress theme.
Installing a theme is easy. You only need to browse through one of the theme galleries that are listed from page 4 to 11, and carry out the following simple steps:
Visit the WordPress Theme Directory web site at: http://wordpress.org/extend/themes/.
You might find a theme that you like right on the homepage, so just scroll up and down and see what catches your eye. However, don't forget that a theme may look great as a thumbnail but might not be right for your type of content or audience.
You can also browse through the web site for themes based on popularity, tags, or by searching the descriptions (and tags) for words that fit your needs.
Once you've found a theme of your choice, click on its name for more information; as shown in the following screenshot:
You can see how the theme will look in a live blog by clicking on the Preview button. This is a great way to eliminate themes...
