MT-Notifier Settings
Unlike prior versions of MT-Notifier, version 3 does not contain a standalone interface. All configuration of the plugin is done through the new integrated settings, available at both the blog and site level.

While Movable Type 3.2 allows you to disable plugins at the site level, there is no way to do so at the blog level. MT-Notifier, however, includes an option - available at the blog level only - to disable itself. Since by default MT-Notifier is enabled upon installation, if you don't want it to be enabled, you should immediately disable it.

At the blog level, you should also verify the MT-Notifier setting to provide confirmation emails to your users. By default, this option is enabled, meaning any request that comes into the system will require confirmation. In other words, when someone subscribes, a confirmation email is sent to that address so that they can confirm both the existence of the address and the validity of the subscription request.

Also at the blog level, take a moment to indicate the email address to use when sending the confirmation messages, especially if you plan on offering either blog or category level subscriptions that require confirmation. This is because blogs and categories do not have email addresses associated with them (unlike most entries).
Most options are also available at the site level, so they can be set at the site level and then individual blogs can be set to override the options as needed. In some cases, both options must be set.
For instance, in order for a confirmation to be sent, both the site and the blog level confirmations must be enabled. If either is disabled, no confirmations will be sent - subscription requests will be automatically processed instead.
