This is cool but using Ghostery plugin on Chrome (https://chrome.google.com/webstore/detail/ghostery/mlomiejdf...) reveals 16 different javascript trackers and advertising libraries used on this website. I know in the footer it states "Memo from Santa does not store e-mail addresses. We will not send you e-mails apart from the event e-mail, nor will we use your e-mail address for any other purpose." but as this being a free service it's kind of worrying. Should I be worried about giving the emails of all my relatives and friends?
