Choose a user name or nick.
This user name should consist only of the letters from A-Z, the numbers from 0-9 and certain symbols such as “_” and “-“. It may have a maximum of 16 characters. You can do
Register your nick or user name.
Type the following command and replace “your_password” with a password that will be easy to remember, and replace “your_email_address” with your email address.

Check your e-mail and verify your account.
After you register, you will not be able to identify to NickServ until you have verified your registration. To do this, check your email for an account verification code. Please, check your spam or junk email folder if no email is received within five minutes.
Identify with Nickserv.
Each time you connect, you should sign in, or “identify” yourself, using the following command:
/msg nickserv identify Your-Nick Your-Password
Your-Nick is your account-name which is usually the same as your nickname.
SASL is the recommended way to identify, if your client supports it. It identifies you before you fully connect to the network and hence makes sure you’re cloaked while you join channels.
