For current clients you should have an email with your login url to your website 

You should have received login instructions from Liz McLellan Strategy after your site was launched.

In those instructions you have a custom link to your website. If you do not have that information please submit a helpdesk ticket on this page.

If you have the custom login url but, need to reset your password:
1.  open the link
2.  click on the "Lost Your Password" link
