there's a great thread up in the kansas city co-ed forum about stuff that gets left behind after you've been pornsurfing, saving images, or editing docs w/ stuff you'd rather people not know about.
you might want to read it. i added a post w/ other things to "worry" about and cleanup/remove.

what other places need to be cleaned up on a computer after using it for porn or hobby browsing, saving, editing??
