There is a default userlist already built in. Just create a menu item, type URL, to index.php?option=com_comprofiler&task=usersList When that menu is used you will see the default list. If you create a new list you will access it in the same manner but after you select the menu item you will select any new lists through the drop down on the top right of that page. If you want to make one of your lists the default you can do that in the list manager by setting your list as the default.
