How do I upgrade from Legacy Membership to Premium Membership?

There are 2 ways to upgrade your Legacy Membership to Premium:

1. You can submit a Library artifact which, if accepted, will qualify for a year of free premium membership. See instructions below on how to upload the artifact. After you’ve uploaded it, please contact us and we’ll upgrade your membership to Premium.

2. Login and click on “My Profile”, then click on “Upgrade to Premium”. It will take you to a checkout page. Click the “Checkout “button which will take you to a secure page where you can provide your credit card information.
