private topic age

[Lord Evermore]

Any way to make Private Topics not drop off the list at the same rate as regular forum threads? Like if I select to see the last 7 days of topics for the forums, I just do that because there's no reason I'd want to see a page-count of 400 or something, and I don't know if there's any sort of load on the server in figuring out that number before displaying the page; only the most recent threads are relevant as far as me wanting to scroll through and see them instead of searching. But Private Topics drop off at the same rate, and there is probably more reason to want to keep several weeks of threads visible there (especially considering you can't search Private Topics).
