Notifications go to the email address that you gave Skydeck when you joined. To change that address, visit My Profile.
Enter your new address in the box under ‘email Addresses’ and click ADD. Click ‘Confirm this address’ and Skydeck will send you an email to confirm the address is yours. Then click ‘Make this primary’ if you want all your Skydeck messages to go to the new address. If you wish, you can delete the old address from your profile by clicking the red delete button next to it.
You can login to Skydeck using any of your confirmed email addresses.
