The title is pretty self explanatory. I hate my username but I can't change it and the only way to get a new one is to create a new account. but I only have one email so can you make a new scratch account with the same email as another?

Yes, it is allowed.

Thank you

of COURSE its allowed. I have like 30 accounts with the same email. I make another one every day lol

Yeah some websites don't let you, but I already made mine https://scratch.mit.edu/users/Poligonal/
