This plugin creates a user note when an account is activated. This makes it easy for administrators to tell when the activation was done, and what method was used to activate it (ie did the user click a link in an activation email, or did an admin user activate them from the admin panel?)
As of v2.2, the plugin can also send emails to either the user being activated or to the site admins, notifying them of the account activation.
v2.4 adds French and Russian translations. Many thanks to the contributors.
