Now all Intense Debate users can choose to use a Gravatar instead of upload a file for their avatar. Just enter your email address and you’re done. Couldn’t get much simpler than that.
Gravatars used through Intense Debate appear on all comments that a user makes on every site powered by Intense Debate, along with links to the user’s social profiles and other info — all of which goes along nicely with the “global” in Gravatar.
For more details, check out the post over on Inside the Debate.
