Your User Name can be any combination of letters and/or numbers from 6 to 80 characters.
Select something that will be easy for you to remember. You can use your email address if you like, but a shorter name will be easier to use.
Create a password that is at least 6 characters or more and not a common word or a number (this is the same language that is used on the create user page)
Your password protects your privacy! To ensure the security of your account information, don't reveal your password. Never write it down where anyone can find it. Change your password often and be sure that you do not use words that people can guess about you or use numbers in a series. Try using birthdays combined with pet names or sports teams.
