As some of you may have noticed, the forum settings have been changed and avatars are no longer cropped to 100x100 pixels. Instead they are scaled to a maximum width of 150 pixels, with no height restriction (though obviously the mods will intervene if a member abuses this freedom with an overly-tall avatar).
It's also once again possible to have an animated gif as an avatar, though the maximum filesize seems to be a paltry 100kB. If I can figure out how to set it to something bigger I'll let you know.
