Hello - I just wanted everyone to know that your default username and account name is whatever email address you sign up with. In order to update your profile name, you must change it in TWO Areas:
Step 1: Go to your Profile and click the "Edit Profile" to the right of your picture. You can change your User Display name to whatever you want, and then click "Save".

Step 2: Go to "My Account" page and change your URL page, your First and Last Name, and your contact email address and click "update info".

ETA: It's come to our attention there is a bug that is not allowing members to update their community page URL at the moment. We are working with our webhost to get this resolved. Thank you for your patience.
I noticed the "Login Email" doesn't change when you update the "Contact Email". How do you change that?
You have to create a new account to change your login email
The URL field under "My Account" is not editable, and I definitely don't want it to stay my email address. What am I doing wrong?
@Jess Did you manage to change it?
It is also happening to me
and me
Is our email visible to the public? I've changed my username, but I can't remove my email?
No your email address is not public - it is only visible to you! If you want to change your email you must create a new account and then request your old account be deleted. Thanks!
I also cannot update my URL, just to update the community.
