No one likes the plain boring fonts that are standard with every other standard blog. It is so much fun to change things up. Even if it is just the titles that are different. Always remember to choose something that you can read, because if you can't read it neither can anyone else.
You can change your font in several areas. In order to change your font you must click on DESIGN then on Template Maker. Then click the advanced button. All fonts can be altered in this tab and this tab only.
You will also notice you can change font colors in these areas as well as font size
