This is a list of business tool and business opportunity reviews. I joined, used, and may still be (or not) using these programs. I recommend that you visit the websites as some of the reviews are several years old and have not been updated. For example, Dr. Lant retired and no longer actively runs WorldProfit. And the Jaaxy Keyword Research Tool has been upgraded and given a fresh look.
As always, do your homework and do not spend more money than you can afford.
