One thing I've really wanted to see done on the website is a mass game of Mad Libs.
We could have the word categories posted in an article on Hellogiggles ("this story needs 3 nouns, 7 adjectives, etc." or have a list and fill it in as we get closer to finishing) and have people comment with what words they want used. Then we could publish the final product on Hellogiggles and people can see whose words made it in, and everyone gets published (in a way)! What do you guys think?
