The most common way to do it is to use your first name. So if your name is 'albert d'souza.' you could use 'email@example.com'. Also, first initial and last name works, 'firstname.lastname@example.org'. Some people like to use their initials 'gh@email@example.com'. You can also use a nickname or word that you like. 'TheRock@email.biz', 'Bigcat@email.biz' or whatever fits your personality.
Other people asked questions on various topics, and are still waiting for answer. Would be great if you can take a sec and answer them
