Open the invitation using the same professional email that received it. Sign in, review the participation rules and accept them before the invitation expires.
Your role is assigned
The sponsor proposes the role, but the server binds it to your verified account. You cannot change role from the browser. If it is wrong, stop and ask the sponsor to revoke and reissue the invitation.
What you see first
Before reveal, other parties remain aliases. Your home screen opens your next assigned action rather than an administrative dashboard.
