Platinum and Diamond Members have the opportunity to Sponsor members.
Every Superpoints Member needs to be connected to someone to gain Membership.  Non-members that don't have an invite link from someone can request to be invited to Superpoints.  Once they complete the invite request form and validate their email address, they are put into a sponsorship queue.
People that enter the sponsorship queue are automatically sponsored by current Platinum and Diamond Members, in order, one at a time.  Once every Platinum and Diamond Member has sponsored someone, the process starts over.
Platinum and Diamond members receive Superpoints when they sponsor a new member, and also get all the benefits from the at new member like winning on the SuperLucky button when they win too.
