From fd5d923c6bb3c22eb265dd45466dedea7d85d0dc Mon Sep 17 00:00:00 2001
From: Adrian Holovaty <adrian@holovaty.com>
Date: Fri, 4 Aug 2006 04:18:12 +0000
Subject: [PATCH] Fixed #61 -- No more editing hashes when creating users via
 the admin. Created a special-case 'Add user' admin view. The change form
 still displays the hash, for the moment.
