I have email with my own domain @ sergio mydomain. But I'm using blogger and wordpress, and to have this email I set it up in zoho mail because it gives the right to configure the domain. Many should know or have used it. But I want to increase the number of people who are participating in my project and I would like the login screen to hide the @mydomain just for people to type the login, type like gmail, bol, does. Because all emails are from the same domain, you do not have to type @mydomain to log in. Too easy.
So I would like at least one course, how to figure out how to do this.
