The organizers of an event can send you an invitation to access the event's team space, but your Qoezion account is strictly personal: the organizer cannot create an account for you.

When you click on View the invitation, enter your email address to sign in or create your account if you don't have an account yet. You can also click on Continue with Google/Facebook to sign in or create your account with Google/Facebook.

Once you are connected, click on Access my teammate space to access the teammate space of the event that invited you.
