Most services which use Eventz.today Platform require users to create an Account and a Profile.
Account is personal and created with your email address.
Profile is created for an organisation, business, charity or a place
Events can be created with a Profile.
If the service only allows you to create a Profile it means you do not have any Profile priviledges assigned to you. You can either request to be given Editor rights to an existing Profile or you can create a new one.
