We have requested that this feature be more readable. In the meantime, there is an option there for you to get a new word. To the right of the box where you enter the words you see are three little icons. The top one is of two arrows making a circle. Click it to Get a New Challenge aka new words. The second is a picture of a megaphone to Get an Audio Challenge. And the circle with the question mark is for Help. Hope this helps.
I know it's hard to tell as well when the email has been sent because the page just refreshes kind of implying you need to submit again but underneath the captcha in bold will advise when it has been sent. It will say, Your message was successfully sent. You may go back to the page you were on or you may send e-mail to another friend(s). This has also been reported to make more apparent. If you get this message and your friend is still not receiving, have them check their SPAM/JUNK folder.
