I ended the day Googling around for Shareware author info. Here's what I dug up.

Download.com charges $99 for you to list there, and at least one guy claims they wouldn't list his product and kept the $99. Great.

Search Sites is a freeware (Windows) tool that'll check out popular shareware listing sites to see if your app's listed.

Shareware Tracker will go out to 314 shareware listing sites and register your product at the touch of a button (give or take). It's also $89. Sounds like a scam or a great shareware product!

The Stanford Web Creditbility Research site. Wack.

Page on Google with beta release software, and another site on beta testing resources.
