There is also a free font giveaway of the week over at Font Bundles. These are high quality commercial fonts that are free only for a limited time, and you will not be able to download them later, nor will they show up as one of your purchased fonts in your account. But, these free fonts come with a fully commercial license and are worth the effort to grab.
You can access the free font of the week at the following easy-to-remember short URL:
This week's free font is Millenia...
Millenia is the Free font of the week (free for another couple days or so), over at Font Bundles (.net). It's a nice serif.
