To change your email address, first login to the site. Click the “Edit Profile” link in the upper right hand corner, and then choose the Email tab. Note that there are two email addresses here – the first one is a public email address – this is the email address that is shared with other members of the community (leave this blank if you do not want to share your email address). Towards the bottom is a private email address – this is the email address used by the system to send you email.
