The manual notes interface allows you to add notes to the online version of the PHP-GTK manual. These notes are then shared with other PHP users when they browse the manual online.

Periodically, the developers may go through the notes and incorporate the information in them into the documentation proper.

These notes are only visible at gtk.php.net because that's where the database that stores them is located. If (when) the PHP-GTK website is mirrored in several locations, we'll work out a way of having the notes available across all the mirror sites.
