Why can I not change the email associated with my profile on the Zoho Help Center and Community?

Hey all, 

I was attempting to change the email associated with my account here on Zoho's Help Center, however, the email field is unresponsive. It will not allow me to make any changes. Is the customer login here on Zoho Help Desk no longer independent of our individual Zoho Accounts? In the past, a Zoho account was not required to join this help desk and community, or anyone else's help center for that matter. Has that changed?

If so, when did this change?

Also, if this has changed, can you direct me to the support articles explaining this change so I can ensure I understand the user experience my customers and clients will have when joining my future help center?

Thank you, in advance, for your help and guidance.

Here's to the future!
