====== The Context ======
  * Joomla 1.5.18
  * SMF 2.0
  * JFusion 1.5.5-000

====== The Problem ======
Simple Machines Forum (SMF) changed many of its field names in going from version 1 to version 2.  This killed the JFusion SMF plugin.

====== Solution: fix users.php ======

If there is a proper plugin for my combination of software, I couldn't find it.  I decided to bite the bullet and update the field names myself.  It //seems// to be working.

===== Results =====
  * Usersync works
  * Login checker passes all tests
  * Logout checker passes all tests

Those are the only features I'm using at present.  There are other fields in public.php that almost certainly need fixing.
