DELETING PMS

I know it's not a largely necessary thing compared to other things on the site that are in need of developing, but is there any way of making it so that you can delete PMs in bulk?

I've been silly enough to allow 11 pages to pile up and well, I'd have to go into each PM and delete them one at a time. Maybe something like what we have for the Lockers might be a good idea? Check boxes and what-not?

Anyway, just a thought!
