How can i be the part of hackerearth team?

First get registered for the hackathon. After registering, go back to the hackathon page by logging in with the hackerearth credentials that you initially used for registering. You will find that instead of the register button, you have a dashboard. There you will find all your details, like your submissions, or to add team members button, or a randomised team name which you can now change. If another person has registered, and you are trying to be part of his/her team, then ask them to go to their dashboard on hackathon page, and select the option add members. They can now add you in their team using your hackerearth name or email. You will receive a notification on your hackerearth account and an email to accept this request to be part of this team. Simply accept this and you can be part of this team. You can now access the hackathon page as part of the team. I hope this helps your problem.
