How do I permanently change my font settings for Yahoo! mail?
How do I change font sizes? Good question. Because who doesn't want to put vision tests in their emails? T O C H A N G E F O N T S I Z E click the arrow in the font-size pull-down menu in your Compose window. It's just to the right of the pull-down menu where you select your font. 36-point is the largest font size you can select, and 8 is the smallest. You don't see these pull-down menus? That's because font and size choices—along with other text-enhancement options—are only available in Rich Text mode, not in Plain Text. To select Rich Text, simply look to the right of the Subject: box on your Compose screen, and click the link that says Rich Text. Bingo! Now you should see the pull-down menus for font and size, as well as B for bold, I for italics, U for underline…and many other fun and attractive options for sprucing up ye olde email correspondence
