If you would like to change the default welcome message in magento from “Welcome, Paul Donnelly” to “Hi Paul” or “Hello Mr Donnelly”, use the following snippets within
app\design\frontend\default\default\template\page\html\header.phtml

By default Magento doesnt show the address fields within “Create an Account”. To make the sign up process more user friendly you can enable the address fields by adding the following:
Open app/design/frontend/default/default/template/customer/form/register.phtml
Around line 78
Before

<?php if($this->getShowAddressFields()): ?>

Add

<?php $this->setShowAddressFields(true); ?>

<?php
 
//set length of password
$length = 12;
function randompass($length)
{
 
$chars = "1234567890abcdefGHIJKLMNOPQRSTUVWxyzABCDEFghijklmnopqrstuvwXYZ1234567890";
 
$thepassword = ”;
 
for($i=0;$i<$length;$i++)
 
{
 
$thepassword .= $chars{rand() % 39};
 
}
 
return $thepassword;
 
}
 
//to use the function
$password=randompass($length);
echo "<strong>Your $length character password is:</strong><br> $password";
 
?>

Open app/design/frontend/YourTheme/default/template/catalog/list.phtml
Find (around line 96)
