Vogge, that's a good idea!
We heard back from Digital River that you have already bought for a friend, you'll need to provide them with your order number and password. (If you don't feel comfortable doing this, PM or email me and we'll figure something else out.)
If you are planning to buy for a friend but haven't yet, the best way will be to do it as part of a separate order so they have their own order number and password. Use your own email address if you don't want them to receive the confirmation email. We can switch the email address on the order to theirs later on if you ask us to.
