Hi xCaroline,
Not sure if you're still looking for a solution to this, but www.FontPanda.com does basically what yourfonts does but it's free. They will make your handwriting into a font and then add it to their website for others to download. Hope that helps. Cheers, Nic

@koeiekat, I think you were right. The comment needed some more details about FontPanda.com. Thanks for your feedback though. Also not sure why the FAQ wasn't working for you cause it's been fine for me. Anyway, cheers!

Made a comment yesterday that doesn't seem to have made it through the maintenance. If anyone is still wondering, you can have a font made easily from your handwriting for free at www.FontPanda.com and they'll add it to their site for others to enjoy too (for free, of course). So it's not great if you want to keep your font to yourself but if you're just wanting to experiment without shelling out any cash, it's a good option.
