Changing login screen text to new link

Oh Well

Hello,

We are using external user management, and I would like to use this part of login info 

"Not a member? To request an account, please contact your JIRA administrators." for displaying url/link to password management site.

What I found was reference in file 

WEB-INF\classes\com\atlassian\jira\web\action\JiraWebActionSupport.properties

login.signup and login.requestaccount

Can i add new row with link in it? and where else i will have to change it to replace old text.

Is there a way how could I put link there? sometihng like <a href=url> link </a>.

Thanks in advance
