I would very much like to review this, but it doesn't work for me. They have been trying to get this to work for a month now without success. It doesn't work in Chrome as it just loops and Firefox things like extra fields don't show. (tried on 2 servers)
Other things to look at is that you can't password admin with .htaccess as addons use admin folders. I asked for refund as I did pay for this and they reclined.
