As an edublogs user you now have two avatars, one for your blog and one for your username.
Your ‘blog avatar’ will appear where your blog is listed, for example in the most popular blogs lists on the front page. You can set this in Options > Blog Avatar.
Your ‘user avatar’ will appear where your username is listed, for example in the forums or when you leave a comment on another Edublog. You can set this in Users > Your Avatar.
Of course, you can use the same avatar for both, but you have to upload it to both areas.
We’re implementing this as we’re going to be adding avatars to comments soon and have already integrated them with the forums (you no longer need to sign up for a separate account their either!) The ‘user avatar’ will link to your ‘primary blog’ as set in ‘My Profile’.
Happy cropping :)
