Add and delete participants to and from active events
You can now add participants to an active ChipIn event. On the event status page, select “Edit ChipIn” or select the “invite more participants” on the page. Add more participant emails to the “Additional Participants’ Emails” field. That’s it! Note that you cannot add participants to events where you have specified that participants must pay an equal amount.
Delete participants from an event by moving the mouse over a participant’s name. A menu will appear with a link that will allow you to remove the participant. You cannot remove participants that have already contributed or declined.
