-
Links: <a href="http://apple.com">Apple</a>
-
Bold: <b>Bold</b>
-
Italic: <i>Italic</i>
-
Blinking text: <blink>Please do not try this at home</blink>
Longer answer: It's not 100% foolproof. We disallow certain things, such as <script> tags due to the security risks. If something doesn't turn out for you, just ask us helpers.
