Testing features costs real money, so the things that make this community better pay it back.
Build something new. A public feature that is not already in the library (less than 99% correlated with everything we have) and that measurably works earns its own test cost back.
Get liked. Every 10 likes your posts collect here pay $1 in testing credits.
Share your picks. Make your picks page public and share it — when 3 people actually open your link, that pays $3, once per portfolio. A share nobody opens pays nothing; reach does.
Everything is measured, nothing is on the honour system — and one ceiling holds it all: free credits never exceed your membership price in a calendar month.
Post your first feature in the Features category and it may pay for itself.
