Great job, it sounds like a really hard tests... What I'd do, instead of giving 500k to 1000 people, go to f2p around Christmastime, dress up like santa (PM me for the things you need, I do it often), and give 10k to 50k people. Okay, maybe 50,000 is a lot of people, but you could give 100k to 5,000 people.
