338027 Wordpress plugin upgrade

I need the AZ Index plugin upgraded to be compatible with Wordpress 2.8.2 asap. The original developer hasn't actively been communicating since March 2009. I am currently using the plugin on 2.7.1 of WPMU, so it's critical that the MU capabilities remain intact...meaning the 2.8.2 fix must continue to work on my WPMU install. I don't expect this to be a large project, but it will require someone who is intimately familiar with the differences between 2.7.x and 2.8.x versions of WP. The plugin file is attached.
