Your personal website address (URL) is selected when you setup your personal website.
To do this login to your Jeweler Site > My Account > Personal Website (tab) > My Personal Website Address (field)
The portion that is customizable by you the Jeweler follows the premierdesigns.com/____________ .
For example, premierdesigns.com/JulieJeweler
Prior to our technology launch all Jeweler's personal website URLs were a slightly different format.
For example, JulieJeweler.mypremierdesigns.com
This previous URL format is still functional and it will redirect your customer to your new website (premierdesigns.com/JulieJeweler).
If you notice it is not working please remove any "www" at the beginning and try again.
