i disabled it by going to /customer/home.tpl and commenting out the following.
Code:
{*
{if $login eq "" }
{ include file="auth.tpl" }
{else}
{ include file="authbox.tpl" }
{/if}
*}
just underneath that, you can also comment out the powered by x-cart logo stuff
i'm new, but i think this is the way to do it......
