With the recent update (V3.5), members may change his/her Account Email Address now. The email address is the one for Sign-In and account communication, when you change it, you need to confirm the new email in order to re-activate your account.
Also, some bugs fix and minor updates are included in this update, we prefer not to describe them because they are either too minor or they are kind of internal improvement. It could be too technical or too boring… By the way, we are currently working on some other minor update too, we hope they could be done very soon. If anyone has any advises or find any problems, you are welcome to contact us.
