Wordpress 2.5 and Gravatars

After WordPress acquired Gravatars, the Gravatars feature was integrated into the WordPress 2.5 admin panel. This means that with WordPress 2.5, you no longer need to use a plugin to achieve the Gravatars commenter avatar effect. Here's how:

Modify the backend settings to display Gravatars avatars.

Go to the admin panel - Settings - Reading. Set "Avatar display" to "Show Avatar" to enable the Gravatars avatar service.
