MT Extensions: MT-Medic 1.3.3: Very handy. The only thing you can do when an author has forgotten their password.
“MT-Medic is not actually a plugin but rather a CGI application that allows you to do some usefuly or emergency tasks on your MovableType installation. Currently MT-Medic performs the following tasks: Configuration Listing…Installed Plugins Listing…Installed Filters…Authors Administration.”
I’m nervous about it, so I keep the script handy locally and upload it when I need do something then delete it when I’m done.
