If you are new to testing, are looking for some experience in testing, or just want to have fun breaking things, check out the WordPress Bug Hunt on 5 July 2006. The WordPress clan is holding a Bug Hunt against versions 2.0.4 and 2.1 in true “fixing them as fast as we can break them” style, as volunteer coders will be jumping on the bugs as fast as you can get them logged. These guys would truly appreciate any help you can supply, and you can have some fun unleashing all of those crazy testing / breaking / hacking tactics that sit in your closet.

WordPress is what runs this site, so your assistance ultimately helps me out, too.
