The ones you find in any of the categories are free for personal/non profit use. If you do a search two result windows are shown, commercial and ones found on Abstractfonts. The commercial fonts window has a hide/show option. Click hide and only the Abstractfonts freebees are shown.
Greetings. I'd like to know how to have AF displays only freeware fonts, you know, to save all the work to search. I don't really have an interest in buying any fonts yet because all my works until present time have been volunteer and non-profit. Thanks in advance. God bless you.
