Unused invite

Did you send an invite but the recipient haven't used it yet? If the invite is still valid (it expires after three weeks) you can give it to another person. Just go to Sent Mail, open your invite message and copy the invite link with all those numbers and strange characters. Now you can compose another message, paste the link and send it. Gmail account will be created by clicking it. Remember that this won't extend validity of the invitation link. BTW: how can you know that someone used your invite and created Gmail account? It is very simple. You will receive a confirmation message and your friends email address automatically.
