Donating a Paid Subscription

[3lou 55]

Hey guys,

Is it possible to donate to someone else?
We got the paid subscription system up and running and it works perfectly fine, but we wanna be able to donate for someone else, so lets say my name is 3lou 55, and I wanna donate for Bert, I can't buy the subscription for him without having to log into his account.
Is there a solution for this? And if so, how?

We are running on vbulletin 4.2.2

Thanks already!
