Required. 30 characters or fewer. Letters, digits and @/./+/-/_ only
<p>My username field that I have on my form using django user_auth displays : "Required. 30 characters or fewer. Letters, digits and @/./+/-/_ only" right next to it as shown in the image below.  Anyone has any idea how to hide it or why does it appear on the form?</p>
