Have you ever had a message that a freeware program you run has an updated version and have installed it only to find that it is now restricted in its usage and you have to pay for an enhanced version to get back some of the old functionality?
http://www.321download.com/index.html is a site that allows you to download the last freeware version of several programs including things like Mailwasher where the current free version only allows one account to be checked.
