This project shows the people currently using this project. The reason it keeps removing and re-adding other people's usernames is that the project needs to refresh to remove people who are no longer online. Note: It won't work for you if you're not a "Scratcher" and instead a "New Scratcher". You can check it on your profile.
NOTE: If you're not a "Scratcher" and instead a "New Scratcher" (which you can check it on your profile), then you won't be able to see other people online and others won't see you online.
