O that's weird that people dont thank you after they won, I always do that and am not very good with programming so the person on the receiving end doesnt have to be afraid that it would be a automatic generated thanks would be. It's in my opinion also very ungratefull to not say thanks to a present/gift because that's what a giveaway is you are totally strangers and you get luckily an item, she or he is not entitled to it because of her or his achievements may it be accomplisments at work or her or his birthday. It's just a question of good luck from the receiver and a show of gratitude of the gifter. I hope this all doesnt sound like I am trying to appeal to you just wanted to say stuff about a certain common sense which people should have but are lacking these days apparently
