HI, am trying to edit the welcome email text in includes/language/english/create account

PHP Code:
define('EMAIL_CONTACT', 'For help with any of our online services, please email the store-owner: <a href="mailto:' . STORE_OWNER_EMAIL_ADDRESS . '">'. STORE_OWNER_EMAIL_ADDRESS ." </a>\n\n"); 
i want it to show for example

For help with any of our online services please open a Support Ticket (support ticket will be a link to my help desk eg.
please open a <a href="https://my-site.co.uk/tickets/index.php">Support Ticket</a> )

how would i accomplish this i tried changing it to this

define('EMAIL_CONTACT', 'For help with any of our online services, please please open a <a href="https://my-site.co.uk/tickets/index.php">Support Ticket</a>\n\n");

but it didn't work, i know am close but just cant get there,

also how could i change all the contact email from eg [email protected] to open a support ticket this would again need to be a link to my support desk like above.

All the links in my admin are defined from the store default email address eg [email protected] , i need all these to point to my support desk.

hope some one can help

regards
dave
