Click License Keys under the menu on the left-hand side.
Locate the license key pool you want to issue license keys from, and click Edit.
Under Reserve Key, type the email address that you want to send the license key to.
Click Reserve Key.
Once you've reserve a license key, you can then issue it. Issuing a license key sends an email to the given email address with the license key included.
In the same license key pool as used to reserve the key, under Issue Key, type any Notes you want to include in the email to be sent to the user. If you are returning to this page having previously reserved a key, you might also need to enter the Email Address and the License Key that was reserved.
Click Issue Key. The user will be sent an email with the license key included.
