The link code is in this file
menu_cart.tpl
{if $active_modules.Wishlist ne "" and $wlid ne ""}
<A href="cart.php?mode=friend_wl&wlid={$wlid}" class="VertMenuItems">{$lng.lbl_friends_wish_list} </A><BR>
{/if}
thats whats generating the Friends wish list link.
What is $wlid and what makes it be active/full/ ne "full"
I've never heard anything abot a friends wish list.
how does that work
