I would like to know what the "apple - symbols" mean which we can now see side to the users' flags. For example my apple is green, other users' apples are red or beige. Is this a kind of secret code about the users? On my avatar pages I also have such an apple, for example on my foreign language avatars I have a wormy apple, does this indicate that I am a very bad LingQ - student? Or perhaps I better should say "rather inactive" student.
