You may write in to us at email@example.com. Please indicate what your previous group is, what email address you used to sign up, and our team will then help you change your group.
However, please note that you will remain registered with your previous group until the end of the current month, and your points accumulated in your previous team will not be transferred. Only your activities from this change will allow your new team to move up in the standings.
Finally, the change will be possible only once.
