Yes. All fonts in the NBP Collection are free for commercial use. Some of the older ones (notably "Dilithium Pixels") have BY-NC or BY-NC-SA licenses, but I'm not particularly concerned with their being used commercially at this point.
To be clear, commercial projects include, but are not limited to:
- Corporate identity
- Cover art (books, records, videogames, etc.)
- Non-profit ventures (yearbooks, playbills, programs, pamphlets, etc.)
Can I include NBP Collection fonts in a "50 Great Fonts"-like CD-ROM or digital compilation?
Can I hire you to edit an existing typeface or design a new one?
No, sorry. I'm rather busy at the moment and could scarcely find the time to make this post.
Can I edit one of your fonts?
Yes, as long as you comply with the terms of the Creative Commons (CC BY-SA) Attribution ShareAlike license.
Can I donate to your cause?
No. Please do not donate anything to total FontGeek DTF through PayPal, even if you are given the option to do so! I do not presently have a PayPal account, so you would literally be throwing your money into an empty hole.
