I'd like to see a KB article that offers a quickstart guide for business use of Moneydance. Something that distills the best techniques discovered by the user community for doing this.

Yes, I realize MD is not intended for business use, and you can certainly start the article by explain that intention and listing what functionality is not present and not planned to be added. But MD support have also acknowledged many times that customers do successfully use the product for this purpose. So why force new customers looking to follow that path to have to rediscover the techniques?

The information is largely there in your forum postings. It's just scattered across hundreds of posts that require knowing the right keywords to find.
