13147	auth.UserCreationForm : unicity check on username not necessary	peyman	nobody	"Hi, 

  In django.contrib.auth.UserCreationForm, there is clean_username 
that checks if the username already exist in the db. This should not 
be necessary because this form is a ModelForm and the associated model 
User has unique=True. 

Thanks
