HomeBizTools.com has a lot of great information. But today I had the funny experience of reading an article on their site about envelope stuffing similar to the one we have at:

http://www.workathometruth.com/at-home-job-stuffing-envelope.php

What was funny was that the first adsense ad listed was for a site called EnvelopesAtHome which proudly proclaimed  "Want to work at home? Here is your chance at $12 per envelope!" which seemed to be the exact kind of thing www.HomeBizTools.com was warning against.

That's why I include a warning about ads at http://www.workathometruth.com/Rules.php

There's a lot of good information at HomeBizTools. You just need to be cautious of the advertising.
