Hey @AnamolR, at Codecademy we ask the contributors to raise a PR that traces back to an issue. You can find the issues here. I see that you've raised some PRs that don't really trace back to any issue. In this case, we will have a look at them and let you know within a few days. Please don't close the PRs :)

For now, you can check the open issues, if anything interests you - please comment "claim" on it. Once you have been assigned to that issue, you can raise a PR. Thank you! 😄

Hi @mamtawardhani, thank you for responding 🙂
Would it be helpful if I created issues for each of the PR that I raised? Currently, there's only one issue that's linked to my PR. My previous PRs were merged without an issue being created so that didn't occur to me. Would be happy to do that.
Thank you 🙂

Hey @AnamolR, I guess you can create issues, but once let us ask @Radhika-okhade.

@Radhika-okhade please let us know a solution to this? Should @AnamolR be raising issues or should we raise those for him?

[Radhika-okhade]

Hey! @AnamolR Yes you can create issues for the PR's that you have raised.

[AnamolR]

Great, will be on it 🙌. Thank you both @mamtawardhani @Radhika-okhade 🙂
