One website to remember is 1001freefonts.com, when searching for some fonts i stumbled accross this website between the hundreds of other websites which say they offer free fonts but actualy are not offering such a thing, or very limited. 1001 free fonts is exactly what it says it got, over a thousand free fonts for you to use. Not a new website, but worth sharing with you all.
A lot of nice themed free fonts can also be found here:
