I’ve noticed a few people have smilies turned off in their profiles. The An’jou emotions won’t show up unless you have them turned on, by choosing “Always enable Smilies”. I’ve adjusted the ones that I’ve spotted, however there’s still going to be some profiles that have smilies disabled.
o, that stinks 
I usually just untick the “disable smilies” box if I use one.
I normally use Korean smileys though. ^^ -- >_<
oO
How do you know their original, well, origin is Korean?
Actually they’re Japanese, I believe. Their supposed Korean origin comes from the fact that they seem to have been popularized in the Western world by Korean gamers, since Korea has such a large online presence in games.
