Chat - Preciso mostrar a msg com quebra de linha (trocar /n por <b

Olá pessoa, eu estava muito empolgado com um chat que eu estava modificando para poder usar no meu site, mas tive um problema quando alterei o input text para um input textarea, pois o chat não armazena as msg com quebra de linha.

O que acontece é que eu digito a mensagem usado quebra de linha no campo textarea (onde digito as msg), mas quando a mensagem aparece no chat (local onde é exibido as msg) as palavras ficam uma após a outra e sem quebra de linha.

Esse chat tem que aparecer as mensagem da mesma forma que foi escrito no textarea.. pois a função do chat é exatamente essa dentro do meu site, mensagens simples de poucas linha não vão resolver meu problema.

aqui uma imagem do problema pra facilitar

/applications/core/interface/imageproxy/imageproxy.php?img=http://nsae02.casimages.net/img/2015/02/11/150211111004353380.jpg&key=4383eddc26df5a54b6991d31fa254e1c3e77b3b71efb4a93986a831d1db3c9e8" alt="150211111004353380.jpg" />

O código foi feito para gravar as mensagens do chat em um arquivo txt no servidor...

// gets chat text and sends it to ;php via ajaxF()

function addChatS(text) {
 if (chatuserset == 1) {
 var chat = text.adchat.value.length;

// check number of characters in field that adds chat text

 if(chat < 2 || chat > 15963) {
 alert(texts.err_textchat);
 text.adchat.focus();
 }
 else {

// sends data to Ajax

 var send_chat = "adchat="+encodeURIComponent(text.adchat.value)+"&chatuser="+text.chatuser.value;

 ajxsend = 1; // Ajax busy now

 ajaxF(setchat, send_chat);

 text.adchat.value = '';
 }

 }
 else setNameC(text);

 return false;
}

nessa parte do código eu já tentei fazer varias inclusões de funções replace mas todas sem sucesso, confesso que não entendi direito, e nem sei se a melhor forma de fazer isso é substituir antes de gravar ou depois quando lê no arquivo txt..

então vou add aqui o código completo do arquivo.js quem sabe fica melhor pra voces me ajudarem.

já tentei até um outro arquivo php pra modificar o txt mas não dá certo, alem de demorar muito pra carregar..

Por favor se puderem me ajudar, pois estou com a corda no pescoço por causa disso.. a idéia foi boa mas eu não esperava por isso deve ser uma coisa super simples porem eu não tenho muita experiencia em todas as áreas.

Obrigado desde já.
