Man, I agree he’s generous but we also have to be in limit. Last time he gave his e-books for free (though I couldn’t get it because I was not active and I saw his emails after 2 days) that doesn’t mean that you want everything for free.
Though I agree a giveaway to celebrate the giveaway is good but don’t ask, that is his choice and about his inner feelings. So, wait for his decision and never ask yourself. I guess that’s bad.
