I have a classifieds forum on my site. I'd like users to be able to delete their posts once the item has sold. I see the setting in the CP to allow users to delete posts within a certain # of minutes. I was thinking of allowing users to delete posts within 60 days which would be 86,400 minutes. Would this be a problem? I mean would it cause any strain on my server?

My other idea is that I would just manually delete classifieds posts after 60 days. Any suggestions?
