Open Invitations and choose the Invite to Calder tab, then select Generate new invite.
Calder creates a one-time invitation link for you and copies it to your clipboard, so you can paste it straight into a message. The link already contains your invitation code, so the person you invite never has to type it.
Each invitation lasts 30 days and can be claimed once. You can copy the full link again from the list at any time, or revoke an unused invitation before anyone claims it.
What happens next: the person opens your link, the invitation code is filled in for them, and the first successful sign-up claims it. You will then see them under People you invited.
