Creating a Participant Invite Link allows anyone who follows it to join a discussion with a role you specify (see Participant Rights and Roles). You must have Admin or Owner rights in the discussion to enable/disable the link.
To enable the link, open the Discussion Menu and select ‘Discussion Settings’. Select the ‘Invites & Permissions’ tab. Under ‘Participant Invite Link’, click ‘Enable’ to generate a link. Optionally, you may specify the role those who follow the link should be invited as (it is set to Writer by default).
To disable the link, follow the same steps, this time clicking ‘Disable’.
If you wish to edit the participation rights users join with via the invite link, you may do so at any time in the drop-down menu in the 'Participant Invite Link' section. These changes will apply immediately to any new users who follow the link. Note that users who previously followed the link will retain their old role, however they may follow the link again to update their role if it has been increased (for example, from Writer to Editor).
You can generate a new Participant Invite Link (which will invalidate the previous one) by disabling and re-enabling it.
If a user has turned off the ability for other users to invite them to discussions using their email address (see: Turning off Email Invites), they will not be able to successfully follow a Participant Invite Link.
Alternatively, you can invite new participants directly to a discussion (see Inviting Participants to a Discussion).
You can also generate a Team Invite Link for any of your Teams, which will operate in the same way as a Participant Invite Link - adding users who follow it to that Team.
