I changed my name a few months ago (I think before the last two tests before beta). At the time I think you could only change your name once every month. Since then, I have decided I want a more Glichly name. However, when I go to the button now, it tells me: "You can only purchase one name change petition form every 2 months. Come back in 103 days."
Before the last test, it told me I had to wait 95 days. So it seems to me that it is counting UP.
