Subject: [PATCH] =?UTF-8?q?=E2=99=BB=EF=B8=8F(backend)=20increase=20user?=
 =?UTF-8?q?=20short=5Fname=20field=20length?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The user's short_name field length was set to 20. This is not enought
and we have some users who cannot register because of that. We changed
this length to a higher one, 100, like the full_name.
