Can I change the USERNAME???

Can I change the USERNAME???

I just want to know if I can change the username of any active account in the Zoho CRM, I know that I can change the name, nickname, email, etc.

Please if someone know how to change the username tell me!!

I think that for any company is very important to put in the username the job position, because if someone is fired or quit, you can conserve all the information and assign it to a new person.
