yMail can be used as a spam cleaner for your existing email setup, and also as a standalone email client.
yMail's spam filters use Bayesian techniques. You can show yMail which messages are spam and which are not (before you even download them to your computer!) and each time will adjust its filters to suit. After a few days, it will be able to sort mail quickly and efficiently without any input.
yMail can also be used as a mail scanner - you don't have to use the email portion of the program, just use yMail to preview and automatically delete spam before downloading into your regular email software.
Remind-Me-Please is a freeware reminder program which will give you advance warning of upcoming events, appointments, TV programs, movies, birthdays and so on. Enter one-off or repeating events: daily, weekly, monthly, yearly and specials like 'Every two weeks from 1/1/2002' or 'Third Sunday of each month'.
Editing flight plans and aircraft by hand can be time consuming and prone to errors. There's something about editing a 2.5 meg text file in Wordpad which just doesn't appeal to me, so I set out to write something which would allow me to do what I wanted - namely, to populate deserted airfields with a variety of interesting aircraft.
yWriter is a free novel writing program for authors. It allows you to break your novel into chapters and scenes within chapters. You can reorder scenes using drag and drop, and you can print out a number of reports (summary, synopsis, scene list, work schedule). Gives you a running word count per scene and chapter, and the built-in editor auto-saves your work.
