This simple ocmod updates the related products system to automatically add up to 15 products to your related products on the products page.

It merges any current manual related products and up to 15 random products from the same category as the product being viewed, but this only happens when needed, so for example if you have 2 manual related products it will only try and add 13 more, but if you already have 15 or more manual related products it will not try and add any more.
