The Wix development team has recently been making new improvements related to URLs. As a result, new users cannot change their URLs, although they are still able to change their usernames. Please be aware that if you sign up with the e-mail "", "janedoe" will appear in your URL. This is unfortunate, but at the moment there is no easy solution. The developers are not scheduled to fix this issue until Q2. In the meantime, I suggest that if you are a new user, you sign up with a fake e-mail address that does not have any identifying information. I will let you know once this issue has been resolved.
