Considering the open source nature of this product, you are able to change it manually by altering your War3Source interface file, simply change this line:
stock War3_ChatMessage(target,const String:szMsg[],any:...)
{
if(strlen(szMsg)>176)
{
LogError("Disallow string len(%d)>176",strlen(szMsg));
return;
}
decl String:buffer[192];
VFormat(buffer,sizeof(buffer),szMsg,3);
Format(buffer,191,"%c[War3Source] %c%s\n",0x04,0x01,buffer);
new Handle:hBf;
if(target==0)
hBf=StartMessageAll("SayText");
else
hBf=StartMessageOne("SayText",target);
if(hBf!=INVALID_HANDLE)
{
BfWriteByte(hBf, 0);
BfWriteString(hBf, buffer);
EndMessage();
}
}
