You might have noticed some user icons next to some comments today, this is because we enabled Gravatar support. Gravatar acts as a centralized identity pool where blogs, news sites (and recently Revver.com) can use their service and offer a universal icon for each unique email address. As long as you register on Gravatar with the same email address registered on OSNews, your personalized icon will be shown on OSNews (and on all other sites that support Gravatar) automatically. This is a testing period for Gravatar here at OSNews, and there are no guarantees whatsoever that the v4 version of OSNews will use that icon system or its own. It all depends on the kind of quality, stability and responsiveness we get from Gravatar’s servers. So, upload your own icon at Gravatar.com and test away! Ability to turn off user icons will be built-in on v4.
