These products are distributed as "Shareware". This means you get to try them out for a while before deciding whether to buy it or not. Otherwise, normal commercial practice applies. The Software is not 'free', and it is not 'Public Domain'. If you continue to use it beyond the 28 day evaluation period then must pay the Registration Fee, or stop using the Software and delete it from your hard disk.
I encourage you to give the Software to your friends or clients in order that they may try it out as well. However, you may not charge them for doing so (without my express and written permission), you may not give it to them in any form except that which I send to the on-line archives (without my express and written permission), and you may not give them your registration code.
In summary, I want you to use my Software, and I want you to pay me a reasonable fee for doing so.
I encourage Shareware Distribution via Compact Disc. However, please email for permission first. I usually give permission provided that the only charges levied relate to the distribution media, or the bundled goods (e.g. a magazine), and that the recipient is well informed that the Software is Shareware and they are required to pay an additional charge if they wish to use it beyond the Evaluation Period.
