Follow the onscreen instructions! Your username is saved in a cloud variable for everyone to see once you click the background. Please make sure that you're okay with this before doing it.
After two years, I finally decide to work with cloud variables. This code is almost directly copied from abee's project, all credit goes to @abee: https://scratch.mit.edu/projects/10188030/ Uploaded as a test for @dixiklo. Are you interested in finishing this project? Let @dixiklo know, please! :)
