This plugin allows you to send emails to registered users. You can exclude users and groups, specify message encoding, send as text or/and HTML, attach files and receive detailed reports on selected email. Advanced users can use external emails source.
The Avatars Plugin allows you to attach avatars (display pictures, gravatars, profile pics, etc) to a user, blog, and category. You upload avatars within the b2evo administration, with either a large or small (or both) avatar images. If a large avatar image is specified then lightbox functionality is seen, as when the user clicks the small avatar, the large avatar will show in a lightbox.
The Gallery2 plugin allows including photos from your Gallery2 installation in your posts using the Gallery2 Image Chooser and syncing of users and session info with Gallery2.
This plugin will insert ANY and ALL your favorite social bookmark sites into your posts.
Note: The pie chart feature is broken, but the rest of the plugin works as expected.
