Typography is Language represented as Art. And that's why we love fonts, don't we?
One of my favorite websites for FREE fonts is:
They have a ton of beautiful fonts to choose from with large examples for you to browse through.
If you want one, just click on the Windows Download icon and download the file.
Then, unzip the file and double click on the Font File Icon
I'm on a Windows 7 machine and they added this wonderful window that previews the entire alphabet before you install it. Click on the Install button in the upper left hand corner and away you go!
That's it! Now go back to ProShow and you'll see your new font listed in the Font Drop Down Menu.
Viva La Fonts!!
