How to use a URL shortener

Web addresses (URLs) can be very long, and if you are pasting them into an email, Twitter, or printing them in your newsletter, it's better to use a URL shortener. This creates a much shorter version of the web address, which redirects to the long version. This saves space in Twitter, prevents the problem of URLs breaking when they are wrapped round to the next line in emails, and saves your newsletter readers from typing out the long version.
