Rated 4 out of 5 stars

Reposting as the title is not seen publically and then my former review did not make much sense.

Gravatar needs the email address to be lowercased before making the MD5 hash.
From my testing (and introspection of the code) it seems that this is not done.

Otherwise a nice addon :)

This review is for a previous version of the add-on (0.1.7).
