Because wordpress.com bought gravatar, now gravatar support is native. That’s how I have the baby sloth icon. Anyway, if you want your own gravatar, you can go and register at Gravatar.com. The gravatar is linked to your email address, so if you enter it when you comment, blogs that support gravatar can display it.

Am messing around with themes, so new themes may appear and disappear. Am also working on an index page for the translations/summaries.
