I don’t know if anyone really ever does this, but I thought it was interesting. It is a tool that lets you embed fonts in a web page so that people can see the font you created the page with even if they don’t have that font installed. If someone knows of a more current way to do this, let me know. I was just browsing when I cam across this and wasn’t too concerned about be up to date.
