Our users are not happy with the Greenhopper 6.2.2 RapidBoard's use of Avatars. The Avatars take up a lot of space and do not provide any useful information. An overwhelming number of our users have not specified an avatar so they get the default one. And many of the users that have specified an avatar do not use a picture of themselves hence one still can not easily identify who the person is. One of our rapid boards has 11 columns in it. Unless one expands the webpage to the width of a 27" screen, the avatar obscures userful information.
I see two solutions to this problem. Revert to Greenhopper 6.2 or dig into the code and modify webpage.
