I have just updated my Blogger/Plurk Emoticons script on my Box.net account to add one new hidden emoticon from Plurk. It will be added at the end of the emoticon lines. The new emoticon will look like this . It's like a pirate's captain.
Please note that this script will only work for older version of Blogger editor and it will not work in the current version as it has numerous of changes implemented by Blogger on the new version. So it's your decision to use the old one (which i think is still good enough) or switch to the new one, but you will not be able to use the script i made
