How do I make text superscript or subscript?

Making your text superscript or subscript requires a little HTML know-how, but you can do it. Here's how:

1. Click within your text box to make the formatting toolbar appear, and click the button that looks like this: </>
2. A popup box containing the HTML behind that inbox opens. Find the text that needs to be adjusted, and you'll wrap it in a couple HTML tags that tell it how to behave in the inbox.
3. If you want your text to be superscript, format it like this:
   
   ^{This part of the text} is superscript.
   
   If you want your text to be subscript, format it like this:
   
   _{This part of the text} is subscript.
4. Send yourself a test to see how the text appears in your inbox.
