How can i allow anyone to join ircd-ircu server?

i have installed ircd-ircu on my ubuntu server. When i try to access it then it says username invalid. How can i set it so that anyone that anybody can join.

I want to put the irc server on my website

Can someone maybe paste me how my ircd.conf should look like?

At the moment it looks like

General {
name = "localhost.localdomain";
description = "Debian's ircd default configuration at localhost";
numeric = 1;
};

Admin {
Location = "Debian's ircd default configuration at localhost";
Location = "Please edit your ircd.conf file";
Contact = "root@localhost";
};

Class {
name = "Local";
pingfreq = 1 minutes 30 seconds;
sendq = 160000;
maxlinks = 100;
usermode = "+iw";
};

Class {
name = "Other";
pingfreq = 1 minutes 30 seconds;
sendq = 160000;
maxlinks = 400;
};

Client {
host = "*@*";
ip = "*@*";
class = "Other";
};

motd {
host = "*";
file = "ircd.motd";
};

Jupe {
nick = "A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,{,|,},~,-,_,`";
nick = "EuWorld,UWorld,UWorld2";
nick = "login,undernet,protocol,pass,newpass,org";
nick = "StatServ,NoteServ";
nick = "ChanSvr,ChanSaver,ChanServ";
nick = "NickSvr,NickSaver,NickServ";
nick = "LPT1,LPT2,COM1,COM2,COM3,COM4,AUX";
};

Port { port = 6667; };

features {
"LOG" = "SYSTEM" "FILE" "ircd.log";
"LOG" = "SYSTEM" "LEVEL" "CRIT";
};
