Idea: Link Drupal.org account

People should use their drupal.org username to identify their account.

Implementation

So far, I just changed the field label on the registration form to say "Drupal.org username".

Will this module work? https://www.drupal.org/project/do_username

Registration

Some users may not have a d.o account yet, and clients submitting projects are not likely to.

Data sync

How can we pull useful info from their account, like starred issues, recent comments, etc.

Can this module be used with profile fields to log in with drupal.org username?

Can External Entities module be used to sync drupal.org data?

Validation

How can we verify that they entered the right account?
