Your organisation's name, logo and legal entity —
Organisation.
That is what attendees see; this page is only you.
Which emails an event sends you — inside that event, under
Settings › Notifications. They are held per event because
what you want to hear about a sold-out summit is not what
you want to hear about a draft.
What you may do on a given event — that event's Staff page.
A role is per event, not per account.
