Um, we must be misunderstanding.
Fonts can be in one of five places for them to be recognized by OS X. The first is /Library/Fonts . This directory is NOT in your user folder. The second is /Users/yourusername/Library/Fonts . Obviously this is in your user folder. The third is /System/Library/Fonts. The fourth is in your Classic Mac OS System Fonts folder. The fifth is weird -- make a new window, and go to the "Computer" window by pressing Command-Option-C. Then double click on Network, and then on Library. If you make a Fonts folder in here, they will be accessible to the network.
I don't understand what your problem is, though, nickholl. You might have to relaunch applications or logout when you install new fonts for them to take effect.
