	timer -s (identify, 2000) {
		msg -q NickServ "IDENTIFY password"; // Edit this line.
	}
// Join channels after logging in with NickServ.
} elseif ( $context.networkName == "Rizon" && $str.contains($3, "Password accepted - you are now recognized.") ) {

%msg = $str.replace(%msg, ":code2:", "Emoticon2"); // Repeat and edit this line for each remaining code and its emoticon.
%lines[] = $str.split("\n", %msg);
