username issue

Another thing.
I have only the facebook option active & if someone register with this & not with regular option, the name of his username will be his email address. Why not make the facebook name his username. If is not possible the full name, make it just the 1st name.

I’m using bbpress & when you are viewing the profile of a user who used the facebook option, in the website address bar will show something like this http://www.domain.com/forums/users/namegmail-com/

It is not ok that his/her email is public.

Can i get some help with this?
Thank you!

Have a nice evening.
