Avatars for reviewer profilesNext to a reviewer's name (such as Rebecca), anime.mikomi.org displays an avatar icon.
anime.mikomi.org doesn't provide its own upload feature for these avatars; the site makes use of the ↗Gravatar service instead.
For this purpose, anime.mikomi.org uses your private email for the Gravatar look up, not your public one.
