Currently, when you add a new external affiliate link, it is added to the bottom of the list. It would make sense to add the new link at the top as usually this is the most current offering available for the affiliates.

We are requesting the ability to change the order in which these appear, using a click and drag system.

Currently, the only way to change the order is to remove all the links and replace them in the order that you prefer, which removes the click/opt-in stats.
