Please see the below steps on how to invite a new participant to your event after the event has been launched:

1) Firstly you will need to put the event into edit mode. I would recommend doing this by going onto the 'Overview' tab and scrolling to the bottom of the page and click on the 'edit' button:

2) Once the event is in edit mode, please go onto the 'Participants' tab.

3) If you then scroll to the bottom of the page (below all your existing participants) you will see a button called 'Add New Participant', please click on this button:

4) This will then bring a pop up box where you can add the email address of the participant you would like to invite:

5) Once you have added their email address, please click on the 'Add' button.

6) After you clicked on the 'Add' button, you should see the new participant at the bottom of your existing participants. 

7) To send the invite email to this participant, please click 'save changes'. This will also take your event out of edit mode:
