Back in May 2004, DigitalPoint Forums opened a revenue sharing program that enabled the members share in the Google AdSense revenue earned in the forums. At that time, the idea was unique - Shawn Hogan coded his AdSense system to work with member's Google AdSense publisher IDs. If that member started a thread, his publisher ID would show up 50% of the time when ads are displayed.
A DigitalPoint Forums thread asks members of the forums how much money they have made all time. So I decided to look up exactly how much money I made and I see from day one, I made $5.13. To be fair I only started 24 threads at the forum, so that $5.13 was from only 24 threads.
Here are some of the other responses in the forum so far: - $46.58 - $26.49 - $2.00 - $5.00 - $14.00 - $2.80 - $0.13 - $0.33
So as you can see, it totally depends on what you put into the forum. The more you put in, the more you get out. You can earn money from revenue sharing forums, but it might not be the most lucrative thing you can do.
