# Invites

Most users will come to Affinity via an invite they receive from an organization.

An invite means that someone has added you as a pending user to their organization using the email address of which you received the invite.

You would accept that invite by [signing up](/product-guides/authenticating.md#new-users) with that email address as a user.

## External Organization Invites

Organizations who have been invited to join a parent organization (external organization model) will have an invite link sent to them via email where they can accept or reject the invite to the parent organization.
