Premium users are given 2,000 Pixiv Points (abbreviated pp) per month, which users give to others they like and support via a "goodP" button visible on each user's user page. It is possible to send anywhere between 10 and 500 points at a time.What is Pixiv ID?
Your pixiv ID is the login ID that you enter when you log in to pixiv. You can also use your e-mail address for this purpose instead of a pixiv ID. However, this will not turn your e-mail address into a pixiv ID. Your pixiv ID is important registration information.
