Since this is the land of Group Eats, I thought I would share a Kickstarter campaign that is along the same line but on a larger scale.
Recipes by People backers contribute £1, submit a recipe, and all of the recipes are compiled into an e-book that is submitted to all the backers.
I really, really like this project. I like the idea of people from around the globe submitting their favorites recipes. I have no idea what they're going to do with the extra funds, but I really don't care. It's a fun project.
