It's really easy to start a genzine. All you need are a couple of neos with lots of time and enthusiasm; a couple of older fen with experience and enthusiasm (not to mention enough fannish contacts to make up a mailing-list); and a certain amount of mood-enhancers and sheer lunacy to get you to the point at which the thing stops being a great idea for Real Soon Now, and starts being a reality. A lot of crudzines are born that way.
