Is it possible to change email on the Epi World account? I cant find how..
You can not do that manual, but you can ask support by sending mail on email@example.com
Actually support will ask you to foloow these steps:
Go to footer (on same page where you are right now) where you see Feedback on Episerver World (in below image) click on click here link
Then Account/Profile issues and describe your issue in text box.
