1. Write codes in the Code Playground. Whether they are simple or complex codes, there is going to be someone who will find it useful, as there are lots of beginners, not only pros. I've noticed the community respects people who actually code, not just learn. Comment on other user's codes, it is always great to get and give feedback on people's work. 2. Follow people who challenge you or you challenge. So you can keep playing with each other.
