We recommend to register with us free of charge. This will allow you to download all your purchased and free materials again at any time. This is especially useful when authors edit or expand materials you have already purchased. You will also find all your invoices and tax receipts in your account. You can also create a list of your favorite materials and follow authors so you don't miss out on discounts.
You can also change your password and your login email address, choose which emails you'd like to receive from us and what subjects you're interested in so we can make recommendations that are relevant to you.
