Inspired by the zine fest I decided that wikibooks (a project by the same people who brought you wikipedia) was the ideal place to create a guide to how to make a zine - so I did.
Not that there aren't a million webpages mentioning briefly how to make a zine, but with a wikibook it can slowly evolve as people add tips and ideas. Hopefully. As with many many wiki-based things, it'll take off or it won't take off; you can never really tell.
