How can I gift a subscription to a friend?

I introduced someone to LingQ and want to pay to upgrade his subscription to premium. How can I do this? I want to fulfil a promise I made to an Ethiopian friend of mine.

Hi! It isn’t possible to do this through the site itself, but if you let us know whether you’d like a 6-month or 12-month membership, we can send you an invoice. Once we receive payment we’ll upgrade your friend’s account.
