+## Postboxes
+
+**Beginning with Bookface 1.6 it will have built-in support for a new "Postbox" feature** that styles a colored background for post content. This is similar to a Facebook feature that is often screencapped to share on other social media platforms, where they sometimes become memes.
+
+Server Administrators can enable support for displaying Postbox for everyone on their server!  There are two options for doing this:
+
+### The Postbox Add-On
+
+This very simple add-on places the Postbox stylesheet in the \<HEAD\> and that's all it does. It does not add an interface for creating Postboxes, but users can still manually create them with BBcode in the Compose editor.
+
+You can go get the Postbox Add-on here: https://gitlab.com/randompenguin/postbox
+
+#### The Zen Postbox Add-On
+
+This not only adds global support for showing Postbox styling it also adds a Jot Plugin button to the Compose editor so users can easily pick a Postbox from a menu and apply it to their post.

+
+The Zen Postbox Add-on is "selection aware" so if you've selected some text in the editor it will be wrapped in the Postbox when you select one from the pop-up menu. If no text is selected it will simply append an empty Postbox to the end of the text area.
