I want a typography logo for an application. If I use free fonts for that, can I just use them directly without mentioning the creator of the free font, or without linking the page where I download them? Or do I have to?
Spiral is right, you have to read the licence in order to see how you can use the font for free. I'm also a logo designer and when I need a free font for some commercial work I like to use http://www.fontsquirrel.com/ - a great collection of free fonts that can be used for commercial purposes.
