Does anyone know if it's possible to search for ONLY 100% Free Fonts on this site? That would be a HUGE help but I can't seem to find a way.

Any idea what "more options" might possibly mean?

Yes, click on "More Options" at the end of the custom line and then select "100% free"

You'll get a result like that http://www.dafont.com/new.php?l[]=10&l[]=1

Oh for the love... Thanks. Completely missed that.

Do not check only 100% free but also Public domain / GPL / OFL. But still, why ask for things that are that obvious. More options, might that mean 'book your flight to Mars'?

(PS. when someone clicks on 100% free, it displays as well the public domain fonts etc. of course)
