Reputation points represent how much a member contributes to the Hackster community. As you add projects, like, comment and join activities on the site, you'll rack up the points. You can look at your activity and point record on your stats dashboard. Use your point total as a badge of honor, showing other users you're an expert they should follow and can look towards for quality content.
Reputation points are updated every 24 hours. If for some reason you think your reputation hasn't updated after 24 hours of your activity, go to your stats dashboard and click "UPDATE NOW".
