This plugin requires PHP version 5.4 or higher.
Assigns an abstract image as user's avatar on registration using Gravatar's default avatars. The images are composed of random shapes, elements and colors in a defined fashion. This allows to easily distinguish users even if they haven't set the avatar on their own.
The abstraction style can be configured in the ACP (identicon, monsterid, wavatar or retro).
The images are purely random (no e-mail addresses or any other information are being used) and loaded over HTTPS.
