Do you wish to change the email address you created your Tolteck account with?
Just follow these steps:
Log into your account
Click on your name (top right corner) and then choose "My Information"
Click on the "Add..." button, next to your current email address
Fill in the "Email" box with the new desired email address
After confirming, you'll receive two emails in order to confirm your new email address.
Note :
You'll always be able to connect into Tolteck with the first email address.
If you already created a new account with the new email address, keep using that new account.
