An IRC command that enables users to register their nick, so they are the only user with that name, helping prevent confusion and false identification. Below is an example of how the nickserv command may work on an IRC server. Keep in mind that not every IRC server uses the same software and that this command may operate differently.
Note: The below commands need to be run from the server window and not within a channel or message window if you expect to see returned results.
/msg nickserv help
The above commands would display the help screen in the main server window in IRC, displaying all of the available commands nickserv is capable of doing.
/nickserv register password e-mail
Above is an example of how to register the nick you are currently using. In the above example, you would substitute the password for the password you want to use to login and e-mail with your personal e-mail address. Most servers require a valid e-mail address that they will e-mail with a verification code.
If the nick you are attempting to register is already being used by someone, you will receive an error similar to: "Nickname nick is already registered!"
/nickserv identify password
Once your nick has been registered, each time you log into the IRC server, if you want to use your registered nick, you must identify with the server using the above command. In the above example, you would substitute password with the password you used earlier to register.
