Hi Patrick,
Glad you like the software!

Obviously that's an unusual request but you can change the quantity threshold at which the link is displayed on a product info page by modifying the file
includes/classes/observers/class.back_in_stock_notificationsProductInfo.php
changing the line:
PHP Code:
if ($products_quantity <= 0
to
PHP Code:
if ($products_quantity <= -2
To change this threshold on other pages (listing pages etc.) would require custom coding of some core files.
All the best...
