We're currently working on getting the invitations & "save the date" cards layed out for the wedding, and I stumbled upon this excellent font site..
http://www.dafont.com/
Seth Godin just happened to mention it yesterday. Great timing!
Great resource... easy to browse fonts, custom text displays, none of the typical popup/spyware/crap you get on other "free font" websites.
If anyone knows of any others, feel free to discuss below.
