It might be obvious, but we'll explain in any case.
Members are people. They want to drink your wine, give it as gifts, or just build out their cellar. These people become members once they've joined your club by signing up for a membership.
Memberships are what are batched and processed. Once orders are created, members will receive an email letting them know their membership was processed successfully.
If a member has multiple memberships, they will be listed multiple times on the Memberships page.
To view your memberships, you can click the Members tab from your dashboard in Bloom, or click on the members link within a level on your Wine Clubs page. When you view a membership in Bloom, you have the option to just view the member details, which will include the name, email, and date of birth of the member.
