Make username the first field in the sign up forms

[probus]

I propose we make Username the first field in the sign up forms, because that is the most important field in the mind of the user (i.e. registering a username for themself).

The email field is currently not validated in the facebook sign up form (below). We had a user who I assume typed their preferred username into the first field and probably never even looked at the labels or other options. I think it’s a fair assumption, but it probably never comes up for others because the validation stops you from submitting the form.

Proposed order:

Username
Name
Email
Password

Current form:

Couple a minute ago, we setup login via Facebook as you mentioned here. I’m trying with another facebooks ids for a test user sign up but after click on Okay on Facebook pop up window it is inserting or taking two things username and Name only from Facebook profile and email box is blank why?
Why not picking email from Facebook?
I’m confused about that please see the below image, which I captured after click on Okay button on Facebook pop up window. Below you can see that, email box is empty.
