As of June 2019, Albums and Crates all became Collections. Any Albums you compiled are now Public Collections. If you had any Crates, they are now Private Collections. All your Collections can be found here: My Collections
As you find Records on the site that you wanna set aside for later, you can put them in either a public or private Collection. Just click the 'Add to Collections' button on a Record page or the (+) button on any Record to add it to one of your Collections.
If you have any questions, please send an email to firstname.lastname@example.org and we will get back to you as soon as possible.
