I've been trying to make one, but the server at the site has been too busyChurch Sign Maker - Make Your Sign
Make your very own church sign, kinda like the ones you see here. Just enter some text and click the 'Go' button.
There are 12 new designs (and 5 "classic" designs) to choose from.
There's also a Church of Scientology sign maker, a Westboro Baptist Church sign maker, and a letterboard maker.
