Often we'll realise our stock count was out by one or so, so we'll add 1 to the stock level so we can add a product to a specific order.

The only problem is that this presumably emails the whole list of people waiting for that product to be back in stock, and then takes them off the waiting list for when the product does actually come back in stock later!

This should be a really easy fix (heh, heh I imagine!) that would just be a checkbox so that VM only ran the "update users waiting for a product" code if the checkbox was ticked (on the product update page).
