I don't know if everyone knows about this, but i just recently found out that Hikaru-san is very good at using alt codes. Most of the smilies in her blog are from using alt codes.

If anyone is interested in knowing the list of alt codes available, the links below might help. Hope that by directly posting the links I am not breaking any forum rules. *crosses fingers*
