Copy & paste the code located here into Notepad, Wordpad, MS Word, or whichever program you use.
A line of code like the following represents each mood in the theme:
The bold number, 3618, is my personal theme ID. Everyone has to find their own theme ID, which is easy to do. Just go to your LiveJournal Console and type---> moodtheme_create juc juc then click on execute. Your personal theme ID will appear.
Go to the text file you've created with the code. Replace all of the 3618's with your own theme ID number.
Again, go to your LiveJournal Console. Copy & paste the code with your theme ID into the console. Click execute. Each of the moods are now associated with the mood icons. You now have access to the JuC LJ Mood Theme!
To apply the theme to your journal, go to Modify Journal. About halfway down, there's a box marked Select mood icon set. On the very bottom of that pull-down menu should be juc. Choose that, click on the button to save changes, and you're done!
