I want to change my username,  I think it's easy because the website isn't old.


As you've mentioned, we can do that at this stage but not in the future..
Please comment here or message me with your preferred username so I can change it for you.

I think it would be cool if the users can change their usernames maybe like Facebook one time every 60 days or maybe at least once a year like Codeforces.

We'll take that into consideration as a feature in the future.
