Okay, so last month, I didn't really post much in the forums, which was a mistake on my part.
The amount of effort it takes to either start a couple of threads, and respond to a few more is nominal. As long as you make a habit out of things, it becomes easy to make the extra 3 dollars a month for posting in the forums, $4.50 for the PTC Daily, and another $0.60 for daily emails. That's another 7 bucks in your account, just for doing what you already do!
Here's the trick. When you go on the computer to check your email, first click on the daily email, and click the advertisement to confirm the email. If you notice. when you click the ad, it opens a new tab. You can close this, and then open the forums link with the middle-click button. You now have two windows open, the forums, and the main site.
Next you can go to the Offers > Dailies section and do the PTC. If you're not familiar how to do the daily PTC, there are plenty of guides on the forums.
Now make a post, let people know what you did during your day, or something new you saw, and you're off on your way to make that much more
