It works as advertised for a feature that should be part of ios5. No settings to configure, just select your meeting and an email opens. Pretty annoying that you pay $2 for an app and they shamelessly put an ad in the footer of your email. No way to turn it off, just have to delete it before you send the email. If they give the option to disable that I would give another star.
