We will shortly be replacing the stock avatars that you can select for your profile.
First to go will be the flags.
All flags in the 'fmf flag set' will be removed in the next couple of weeks.
There are new flag avatars available in the 'Flags of the World' set.
If you currently use one of the stock flag avatars, please change it over to a new one.
You can change your avatar by selecting my fmf at the top of the page and then Edit Avatar Settings in the profile menu.
