Vouchers can be used to encourage new users to register, and award points for doing so. The register and redeem component lets you create a workflow where a new user can enter a voucher code, and will then be prompted to enter an email address. If they have an existing account, they will be asked to log in. Otherwise, they will be asked to set a password, and will then be logged in. They can also be awarded points for registering.
To get started, install KVoucher if it isn't already installed in the relevant website.
Remember to create a new version of the site to make the changes in if you are editing a live site.
1 Go to Website Manager, then Websites, and select the relevant site.
