Buying Jr VIP for someone else?

I figured that there is not much point in paying for Jr VIP and premium membership for myself at the same time. I don't want to stop supporting the forum with those contributions though so instead of getting both for myself I'm going to renew the Jr VIP and pay for someone else to get it too.

My renewal is up on the 20th for my premium membership so I have stopped the auto pay on that and want to help someone become Jr VIP instead. How do I do that, can I just pay and put someone else…
