When I started the app today, it said some thing about a $5 bonus. Was that for joining the forums? The popup went away, and I didn't see it again after rebooting
If it was a "bonus," you should be able to access it by tapping the "earn more" tab at the bottom of the app's home page.
Perhaps it was a pop-up about the MidWeek Money Maker? Mine is $5 for 18 offers.
Sometimes I have to logout and back into to the app to see my bonuses.
I'm guessing it is for your midweek bonus.
mine did that too, fine print said forums users earn $5 more on average.
I got that too and I think it just says that on average forum uses earn $5 more by learning what others are doing to save $$
