You can easily change the style of your blog entry text, and even add links and emoticons ("smileys"), using the buttons in your Blog Entry toolbar.
When you add or edit a blog entry, you'll see the text toolbar at the top of the "Entry content" field. To learn more about a button, hold your mouse over it.
To apply a format or style change to some text, click your mouse before the words you want to change and, holding down your mouse, drag your mouse over the words to select them. Click a toolbar button to apply a style to those words (click the B button, for example, to make that text bold).

To insert an emoticon, click your mouse in the entry field where you'd like the emoticon to appear, then click the "smiley" button on the toolbar.
You can quickly add a link by simply typing the web address of the page to which you want to link, or by clicking the link button and entering a web address in the field provided. Learn more.
