[Authors' org.] Novelists Inc.

Their FAQ page is pretty clear on what they offer and why. But Victoria is a member, so I expect she'll be along presently with her impression of their services.

Or you could, like, Google. Or go to their website and read about what they offer, to whom, and so on. Y'know, due diligence? NINC has a really quite good reputation.

It's a professional organization for writers. There are rather a lot of them, and most of them have both a membership fee and requirements you're expected to meet. In return, you get various benefits, like possible access to medical emergency funds, legal defense funds, industry information publications, and etc. That's not in opposition to Yog's Law, Bart, in any way. They aren't a publisher, agent, display site, reading-service, fly-by-night editorial service (don't be confused, by this, though -- there ARE reputable freelance editors and book-doctors, both, as well), or other such dubious enterprise.

For the record, I'm damned careful about the ads I accept for the forums, and have a list of blocked Google advertisers that's as long as my arm. If you guys see a sketchy Google Ad (beyond the usual "Self-Publish for Fun and Profit!" ads), drop me a note. There are a handful of places that change their advertised domains frequently specifically to get around the censors.
