Shareware distribution gives users a chance to try software before 
buying it. If you try a Shareware program and continue using it, you 
are expected to register.

Individual programs differ on details -- some request registration 
while others require it, some specify a maximum trial period. With 
registration, you get anything from the simple right to continue 
using the software to an updated program with printed manual. 
Copyright laws apply to both Shareware and commercial software, and 
the copyright holder retains all rights, with a few specific exceptions 
as stated below. 

Shareware authors are accomplished programmers, just like commercial 
authors, and the programs are of comparable quality. (In both cases, 
there are good programs and bad ones!) The main difference is in the 
method of distribution. The author specifically grants the right to 
copy and distribute the software, either to all or to a specific group. 
For example, some authors require written permission before a 
commercial disk vendor may copy their Shareware. Shareware is a 
distribution method, not a type of software. 

You should find software that suits your needs and pocketbook, whether 
it's commercial or Shareware. The Shareware system makes fitting your 
needs easier, because you can try before you buy. And because the 
overhead is low,  prices are low also. Shareware has the ultimate 
money-back guarantee -- if you don't use the product, you don't pay 
for it.
