Hi Nathan,
The current settings on the website do not allow users to change their login email manually in the profile section. However, we can do it for you if you send us a request by email to support@xceed.com.
** Quick Tip: Clients with an active support subscription should be sending their questions by email if they wish to benefit from the faster response time. Thanks!
