Auto Delete a Post on a given date

[zimdude]

Please can someone advise where I could find this or have it written;

I want the ability to delete a specific post on a given date. SO when the user creates a post, there will be a date field which they can enter the date that the post will deleted. It will need to be for a specific forum and its child forums.

We want to post educational courses and have the posts auto delete once the course date has passed to minimize the manual cleanup!

Many thanks
