Aah, I see what you mean now. It makes sense that promotion.php should update ranks. Here's the thing though, I'm using Ranks differently.

Users subscribe to a Rank, by purchasing a Paid Subscription.
The subscription script adds them to a new rank (through the use of an additional user group), e.g. Paid Rank
When they purchase the Paid Rank subscription, they are automatically given the rank of Paid Rank and their new Rank is displayed correctly.
However - and here's where I'm facing the issue - when their subscription period ends, the rank is not removed. Their profile and posts still show Paid Rank. promotions.php does not update (remove) users from Paid Rank after expiry of their Paid Rank subscription.

What works for now is either:

a. Manually go to Admin CP, user's profile, and just hit save, or
b. Manually run "Update user titles and ranks"

I'm looking for a script that can essentially automatically do what "Update User Titles and Ranks" does, and run it every night, instead of running it manually.

The obvious response is: "You're doing it wrong, you should be using User Titles for this". But I need to use Ranks for this, because users are essentially purchasing Custom Titles using a Paid Subscription, and their original User Title is becoming their new Rank, so basically someone who is:

Username
Premium Member

can buy a Paid Subscription for Custom Title and become:

Username
Custom Title
Premium Member

(where Premium Member is the Rank)

So, my question is: Is there a script that does what "Update User Titles and Ranks" does? Or is there another approach that can solve this issue?

Thanks.
