Hello,
I had a problem. I wanted to use Youtube icon from Font Awesome but insdead of icon I got squere. That happened with bunch of them. I tried lots of things and I gave up.
Today I wanted to implement new font to the website and I saw the Font Awesome in the /fonts folder and that's when I got it.
All you need to do is this:
1. Download the latest version of Font Awesome from http://fortawesome.github.io/Font-Awesome/
2. Unpack it and from the folder /fonts copy all the files (five of them) to ROOT/gk_creativity/fonts (overwrite them)
That's it! You can find the character code from here - http://fortawesome.github.io/Font-Awesome/cheatsheet/
Just replace "&#x" with "\"
example:  should be \f00b in the gk.stuff.css
I hope this helps someone.
Cheers,
Gorast
