All participants registering are allocated to the same group, see the same sessions, and fill in the same demographic data. However, it is possible to divide the registration system up into different parts, which are called accounts. A single account system allows an organization to offer open self-registration. Tests are available to all comers, but test takers must provide some information, for example name and address, so that the organization knows who is taking its tests. A multiple account system allows more complex self-registration.
Different departments can have different registrations.
Or a service organization can provide accounts that are different for different customers.
