How to change my email address ?

I looked in the Basic RIU functions and FAQ and didn't see how to change my email address . I might have overlooked it idk .
But can someone please tell me how to change my email address without having to delete my account and creating a new one ?

Just hover over your user name in the upper right and click on Contact Details. There you will see the first box is your email address.

Thank you . I was struggling over that lol
