Minotar enables the use of Minecraft avatars in WordPress.
Minotar gives you the option to replace the default avatars found in WordPress with Minecraft avatars. The API used is found at http://minotar.net and can be used freely by anyone.
The avatars is taken from the Minecraft equivalent of users and comment posters, if a commenter uses the name Herobrine on a comment the skin of Herobrine in Minecraft is used as an avatar.
Note: The avatars are case-sensitive. Eg: notch and Notch are different names.
