Avatars not resized?
Shouldent user avatars be cropped automatically to give the user an interface to do it or set dimensions to be equal?
Although I am only using the Imgur plugin for handling images, I would have thought the avatars could be cached at a squared size?
a 140x250 avatar is contorted into a 64x64 image here, that shouldent be the case?
