I have read this response several times and still do not understand how this works.  I have a small shareware multiplication tables learning program I wrote for my children.  I do not wish to be a spammer.  How can the program have an individual page at software.informer.com without it being downloaded (sounds like a chicken versus the egg situation to  me)?  I apologize; I am very new at this.

It's a case of divine intervention, so to speak. )
As a rule, the individual pages on software.informer.com provide links to first-hand resources, without hosting anything (which is a nice way of preventing users from questioning the origins of listed programs, I'd say); so it is probably implied that a program (and, likewise, its developer) has an official website, where it is hosted or linked to. It is there where it's to be first downloaded from, I believe.

In the same breath, since the requirement is as low as 'at least one user of siClient', you yourself can install your own application alongside siClient - and it will probably pop up on the website.

A program gets into our database automatically after it is installed by at least one user of siClient.
You can use the 'Suggest a correction' link found on the program's individual page at software.informer.com and provide any description you deem fit.
