When someone purchases a Gift Voucher they receive an email with a link in it, which they use to Redeem that Gift Voucher. It's then added to their Gift Voucher Balance. Depending upon which version of CCGV you have installed they can then:
1. Go to their Shopping Cart (when logged in) and go to GV Send. From there they can email the Gift Voucher (all or part of it) to someone else, along with a personal message.
2. With a small modification to CCGV they can also go to their Account page and send it from there.
