Thanks.

The same as above in the description.

Presumably we will need tests to show that these work and documentation too.

It would be better to add a patch (svn diff) rather than a file as its easier for commiters to apply.

Change UI/UX from NULL to False.

Change Easy pickings from NULL to False.

django.contrib.localflavor is now deprecated — see ​https://docs.djangoproject.com/en/dev/ref/contrib/localflavor/

A repository was created for each localflavor at ​https://github.com/django/django-localflavor-? (Replace with the country code.)

If you're still interested in this ticket, could you create a pull request on that repository?

Sorry for not resolving this issue earlier, and thanks for your input!
