how can i change my username in mylot?

You can't change your username. Unless you make another account.

too bad for you but once you entered your desired username upon signing up, you can no longer change them. If you really wanted to change your username then I agree to other's response that you will really need to close your old account and open a new one.

As per my understanding we cannot change our user names here in my lot. When you want to change our user name you might need to register again and use the name wgatwgt want but of course that too might violate my lot rules.

Never use your real name anywhere on the Internet. That is just asking for trouble. Unless you have a name like John Smith, you will regret it and probably be cheated or impersonated. If you have a credit or debit card, or even a paypal account (which you must have for mylot!), it makes it much easier for hackers to get into it.

Not going to change the username.

No you can not change your username. Anyway changing your username to your real name is not the best idea. ;) Most of the people who did that regret it.
