Below are a few programs I have written for personal use that I thought would also be useful others. These programs are all free and do not contain any advertising or spyware.

Generic Game Trainer.
A generic game hacking tool that will allow you to cheat in most games. It searches game memory for values like number of lives, money, energy, etc.. and lets you edit them.

Net.Polemics.
A free ISAPI based bulletin board system (BBS) that lets users post messages and reply to messages others have posted. There are numerous uses for this software, including open user discussions, support conferences, "ask an expert" forums, news briefings and more.

DriveSpace.
A simple little program that helps your track down where all your hard drive space is being used. Has an interface similar to Windows Explorer.
