 Account deprecation
-  At the beginning of each year (i.e. early November), to prevent clipper username conflicts, you should run ``$ python manage.py deprecate_clippers``. Every association clipper username <-> user will then be set on hold, and at the first subsequent connection, a verification of the account will be made (using LDAP), so that a known user keeps his account, but a newcomer won't inherit an archicube's.

 Customize
   You can customize the SocialAccountAdapter by inheriting ``allauth_ens.adapter.LongTermClipperAccountAdapter``. You might want to modify ``get_username(clipper, data)`` to change the default username format. This function is used to disambiguate in the account deprecation process.
