How does Incarnate work with Gravatar?
For incarnate, Gravatar is seen as another provider. Gravatar works differently than the other avatar providers, in that it keys off of an email address, instead of a @username. So, if you put an email address into the Incarnate input box, it will resolved to gravatar automatically. If you are using the WordPress plug-in and a user puts nothing into the Incarnate input box, the plug-in will attempt to use Gravatar. However, if the user does use Incarnate, it will override Gravatar and use the “incarnated” avatar instead of keying off the email input box.
