Depending on how the engagement you’ve been invited to is set up, you may or may not be able to share your invitation link with others. A good way to tell is based on how you received the invitation yourself.
If you received a link via an email directly from an organization you are affiliated with, through social media, the newspaper, or any other public channel, it’s a safe bet that the link is shareable with anyone else who has a stake in the engagement.
If you received a link via an email from ThoughtExchange on behalf of the organization that is hosting the engagement (see example below), the link is unique to you and cannot be shared. Unique links offer the ability to participate only as a single individual. If you share a unique link and another person participates in the engagement, they will have the ability to overwrite the information you provided.
The link you received may also ask you to enter a unique identification number (ex. a student or employee number). In these cases, the link itself is shareable, but the person you share it with may not have a code with which to access the engagement.
