If you would like to invite friends to join a group, click “Send Invites” in the Contributors section of the dashboard to get started. (Group organizers can also invite by clicking "Invite People" in the Organizer Controls bar.) This opens a window where you can enter the email addresses of those you’d like to invite.
Optionally, you can include a subject line and/or a message with your invitation.
When you’re ready, click the “Send Invites” button to complete the invitation process. Pay By Group will email your invitation to everyone you’ve included.
You can also invite others to join by clicking “Copy link” on the bottom right of the invitation window; this will copy the address for your group to your clipboard. Then you can paste the address into your own email client, an SMS, or the messenger app of your choosing.
