Embedding Fonts on a Page:
You can embed a whole font in your site, so if a user doesn't have a font, they can still see it. But, it will have to download.
They must be in a certain format called: .eot converted with a program called WEFT. You can get the program and then convert your own installed fonts. It only workds in Explorer.
