I got the calendar 2008 for free today from FontShop! Thanks. Looking for fonts is always a time consuming activity. I often use the FontShop website to look for fonts or to search for a specific font. On the FontShop website you have large search capabilities, you can search by font, by family, by foundry, how a font looks, etc…
