Yes, you can have other people's registrations on your profile. However, the name, address, and date of birth of the registered person must appear on the registration, even though it is linked to your profile and email address. You can not change the information on a specific subscription and therefore giving your subscription to another person is not possible. Note that you must be at least 18 years old to have a profile on Waitly.
It can be beneficial to have other peoples subscriptions under your profile, if you are the one managing the subscription. That may be the case if you have kids under 18 years old, have close relation to an elderly or simply wish to have one overview of your own and your close relatives subscriptions.
