I provide the content on this website for free, but I earn income and other benefits in the following situations:
1) Whenever someone clicks on a Google Adsense ad,
2) Whenever someone follows an Amazon.com link on this website and then proceeds to buy something,
3) Whenever someone signs up for Dropbox using the referral link provided on this website, or
4) Whenever someone signs up for a DreamHost web hosting plan using the referral code DREAMINTOACTION.
The income and other benefits that I earn do not cost you anything.
