Hi Moose!
I've never tried to get into and modify others profiles,...
I wouldn't touch a profile without a good reason. I used ftp to download your image directly from the server, edited it, then uploaded it again. Probably just as ethically questionable, but that's my story and I'm sticking to it!
Is the black square what you'd like? If so I'll put it back - and we'll change your ID to Darth Admin, moderator of the dark side.
By the way, changes to avatars take effect immediately - you don't have to wait for message pages to be regenerated.
