Re: aldersboy:
After completing the subscription procedure the nickname you gifted a subscription gets subscribed automatically (after some period of time, depending on subscribing method), there is no need for the subscribed person to approve the subscription or do anything alike to get it. As for whether they are told who gifted them the subscription or not - well, they might be, if you tell them in e.g. flyordie chat rooms :), but I doubt it appears on their login page/status page.
Though, subscribing someone without notifying them - seems to be a very strange idea, as for me :). Though, possible...
