Feature request : generate letter avatar photo for user in registration (not after)

Hello,

i think this feature should be a defaut option, you'll agree i am sure
when users register and come to the last step (personal photo or avatar) they see a grey man avatar,
As the letters avatar feature already exist, i suggest to generate the avatar in this step when user are invited to upload their photo.

Its more friendly !
