One of the coolest projects that the Automattic team have worked on is Gravatar which lets you upload a picture or avatar of yourself and use on various sites around the web. So when you comment on a Gravatar enabled site, your picture will appear beside your comment. We now have full support for Gravatar in the comment streams of PollDaddy Answers. If you would like to create your own Gravatar icon you can do so here.
Please visit our support docs for the most up to the date information.
