It is imperative that you check your spam or promotions folder if you don't see that automated message in your inbox!
Several email providers block most of our automated system messages. We can not override such a block. Some email providers only show your spam if you login to the WEBMAIL site, they won't even pass it to your device.
After logging in to the Members Site, you can change you password on the 'My Account' page.
