A great email generator is www.mailinator.com.
It allows you to create an email address if you want to test drive an app, or create a QBO test company, without having to use your regular email address. The email addresses allow you to check any messages you receive, and the messages are automatically deleted after a couple of hours.
Caution: It is PUBLIC email, so please don't use it for sensitive info like bank accounts :-)
