Can I Address only First name in Welcome Message?

Hi,

I've searched far and wide for any information or prior case where someone has wanted to address their customers via first name only in the welcome email after registration.

I'd like the email to start with

Hi <first name>,

Contents of email here.

I've found a similar thread here

however my knowledge of coding isn't sufficient to change it around.

Currently the code in the contact_us.php is

define('EMAIL_SUBJECT', 'Welcome to ' . STORE_NAME);
define('EMAIL_GREET_MR', 'Dear Mr. %s,' . "\n\n");
define('EMAIL_GREET_MS', 'Dear Ms. %s,' . "\n\n");
define('EMAIL_GREET_NONE', 'Dear %s' . "\n\n");

Any help would be appreciated

I tried changing that code around trying my luck... didn't work

$name = $firstname . ' ' . $lastname;

if (ACCOUNT_GENDER == 'true') {

$email_text = sprintf('Hi %s', $firstname);

	} else {

		$email_text = sprintf('Hi %s', $firstname);

	}

$html_msg['EMAIL_GREETING'] = str_replace('\n','',$email_text);
$html_msg['EMAIL_FIRST_NAME'] = $firstname;
$html_msg['EMAIL_LAST_NAME'] = $lastname;

Hi again,

in includes>languages>english>create_account.php
I made the following edit

define('EMAIL_GREET_NONE', 'Hi %s,' . "\n\n");

in admin/email_welcome.php

// build the message content

/* if (ACCOUNT_GENDER == 'true') {
if ($gender == 'm') {
$email_text = sprintf(EMAIL_GREET_MR, $lastname);
} else {
$email_text = sprintf(EMAIL_GREET_MS, $lastname);
}
} else {
*/ $email_text = sprintf(EMAIL_GREET_NONE, $firstname);
// }
$html_msg['EMAIL_GREETING'] = str_replace('\n','',$email_text);
$html_msg['EMAIL_FIRST_NAME'] = $firstname;
$html_msg['EMAIL_LAST_NAME'] = $lastname;

However now when test it, the output is (where lastname = cde)

Hi cde,

Why isnt it showing first name yet?
