Here are some things you can do that allow you to personalize your blog:

A. Customize your theme

B. Turn on Plugins 

Plugins add features that you can use. Instructions to turn on plugins can be found here. We suggest you turn on the following plugins:

• Compfight Safe Images: search for images to add to your posts that are creative commons copyrighted (safe to use). They are added to your post with attribution to their owners. Read more here to find out how to use Compfight.
• Supreme Google Webfonts: allows you to change your font style andsize in your posts. Once you turn it on, you will be able to choose the font family and font size when writing blog posts and pages.
• Image Widget: Makes it easy to add images and badges to your sidebar. After activating, look for the Image Widget under Appearance > Widgets

C. Customize your widgets

Widgets are the webparts that are part of your side bars. You can learn about widgets in the video below.
