I would like Tom Fulp and the developers of Newgrounds to consider making a "custom user-made icon system" which allows user-made icons (esp. expresicons AKA emoticons) to be posted on the forum and other parts of this site.
If this system was implemented, many artists who upload their original artwork at NG may get their work discovered even more easily than at normal art forums which tend to have boring default icons (e.g. yellow smilies). So in a moment, you'll see an example of the type of code & custom icon NG-users could use at this forum etc., if NG developers ever made this dream into reality.
To post my "Never Been Kissed" expresicon (emoticon), users would type anything like :O3o: or :iconO3o:
