When you create a WHYPAY? account via the website you are automatically assigned as the Admin for your account.
If you upgrade your subscription from the Free plan to the Plus or Pro plans, you'll be able to add others as conference organisers on your account. The Organiser will receive an email inviting them to set a password and log in.
Organisers differ from Admins in that they are only allocated one conference room from the Admin's account, and cannot access or edit other conference rooms. They also cannot edit subscriptions or billing information.
Admins cannot edit the conference room settings of their Organisers, but they can choose to delete their organiser altogether if they wish to.
