Be sure to stay to the end of the credits for any Easter eggs!
EASTER EGG: Sign up for the (low volume) mailing list on https://www.milesoneal.com/ . Mailing list members will get special offers and contest notice now and then, as well as news from the author on future products, special events, etc. Once signed up for the list, you may select which types of email you are interested in receiving. (Original text included a chance to win prizes. That period is long past.)
