how can i change my mail

Good question. It used to be changeable under Account->Settings. But now I find I can't change it either. The field to enter or change the e-mail is greyed out. Must be another bug. You should probably contact support to change your mail.

thanks, i will

Thanks to the site's redesign, the ability to change e-mail manually has been temporarily disabled. The only way to change your e-mail now is to contact support.
