Ever wanted to create your own font but then realized you have no idea how to do that? I feel ya, friend. And I'd like to suggest you check out FontStruct. FontStruct is pretty intuitive and easy to use for even (and perhaps especially) novice font designers. Fonts you design can be installed on any Mac or Windows computer.
What I think is particularly nice about this tool is the social aspect. After you've created your font you can choose your own licensing for the font. This means you could protect the font with an All Rights Reserved copyright (preventing downloads), or you could share the font (making it available for download) under a variety of Creative Commons licenses.
The ability to share fonts means that not only can you create and share your own fonts, but you can also download fonts made by other users who are willing to share their work. Make sure you check the license for each font before you download and use it; I was able to find a decent selection of fonts available for commercial (and non-commercial) use.
To find a font, click the Gallery tab on FontStruct. From there you'll find fonts divided into a few categories: What's New, Top Picks, and Everything. You also have the ability to search, but I do wish the search feature was a bit stronger and had the ability to search by license type. When you find a font you like, click its title to access the font's page. From there you can download the font, rate it, and see more information. Be sure to check the Shared section for licensing information. Each license is a clickable link, so if you're unsure what the license means, click the link to learn more.
