GitHub does not have a built-in direct messaging feature like social media platforms. However, there are ways to communicate or reach out to users:
- Navigate to your desired repository.
- Go to the 'Pull requests' tab.
- Select the pull request.
- If you and the other person are working in the same repository, you can tag them in issues or pull requests by typing their username.
- You can mention the user by typing their username.
- Once done, click 'Comment'.
- By following these steps, you can communicate with the user by mentioning their names in the comment section.
