The full roster of members on your site is listed under Constellation > Members. Memberships for all plan are listed — so if a member has memberships for multiple plans, they will be listed multiple times.
When clicking on a member, you’ll see a more detailed membership page, where you can view profile fields and plan details. You can manually adjust start dates or expiry dates for the membership, or transfer the membership to another user.
When a member belongs to multiple plans, all memberships will be listed as tabs in the plan box, so that you can quickly switch between plans for this member.
