Freeware means that the application or software is free but usually only for non-commercial use. If you are a commercial institution wanting to use an app listed as freeware, please consult the developers first.

Shareware typically entails a thirty day free evaluation. If you like the application and will continue to use it, please support the developers by paying the price associated with that application. This helps encourage the continued development of software you use. In many cases, support, manuals, upgrades, and other benefits can be obtained by purchasing the shareware applications.

Donation-ware means that the software is free for use, but if you enjoy and regularly use the program, then please be sure to donate to the developers. A little cash infusion is the best way to insure that your favorite programs will be updated and improved in the future. Speaking of which, a little donation here every now and then wouldn't hurt, either.

Commercial versions, or registered versions, of many freeware and shareware applications are also available. Generally, the commercial version of the software offers advanced or enhanced features of the shareware or freeware application. For information about purchasing these products, please contact the developers.
