Tips for picking a username:
Your username is the name your followers use when sending @replies, mentions, and direct messages.
It will also form the URL of your Twitter profile page. We'll provide a few available suggestions when you sign up, but feel free to choose your own.
Please note: You can change your username in your account settings at any time, as long as the new username is not already in use.
Usernames must be fewer than 15 characters in length and cannot contain "admin" or "Twitter", in order to avoid brand confusion.
Important information about signing up with email address:
An email address can only be associated with one Twitter account at a time.
The email address you use on your Twitter account is not publicly visible to others on Twitter.
We use the email you enter to confirm your new Twitter account. Be sure to enter an email address that you actively use and have access to. Check your inbox for a confirmation email to make sure you signed up for your account correctly.
