A clear typographical error was discovered yesterday in the latest issue of MangaMash, a fanzine devoted to hardcore Japanese speed metal bands and Sanrio/Hello Kitty novelty kitsch products. The error, an obvious incorrect usage of your instead of youre, shocked and disappointed MangaMashs estimated dozen readers, who for over 11 months and three issues have come to value the fanzines commitment to journalistic excellence. MangaMash's dozen readers reacted in varied ways to the fanzine's typo. (See text right.) Some expressed anger while others were not lucid enough to give coherent responses. I guess I just missed that one, said editor/writer/publisher Dave Pelks, 20, who usually tries to read over the paper before taking it to the copy shop. Its youre and not your? I always mess that up. The typo marks the first error for MangaMash since last years April/November issue, in which New York was spelled New Yrrok. That wasnt like a real mistake, said Pelks, defending the earlier error. That time I just totally typed it wrong by accident. I know how to spell New York. Pelks maintains it was late at the time, and he was really tired. To prevent future errors, Pelks has made significant overhauls in the fanzines complex editorial process. I think from now on Im gonna have my sister Anne look it over before I make any copies, he said. Shes only 15, but shes really good at spelling and writing. Shes like the brain of the family. As an added safety check, if Anne is unavailable for editing, Pelks says he will ask his mother for help. Because of the typo, future expansion plans have been put on hold. I was hoping do a color cover for the next issue, Pelks said. Actually, not in color, but on color paper. It was gonna be a big picture of Hello Kitty fighting Ga-mera on green paper. That wouldve been so cool. According to in-dustry insiders, the mistake puts the fanzines rock-solid reputation in jeopardy. This is a serious error, Doubleday vice--president Mar-garet Ferber said. Its Manga-Mashs most significant mistake since two issues ago, when Pelks stapled all the cover pages on upside-down. I totally wasnt paying attention, Pelks said of the incident. Collectors estimate the value of the upside-down cover issue at zero dollars. Despite the most recent slip-up, Manga-Mashs two distributors have vowed to stand behind the embattled fanzine. MangaMash provides the best coverage around of Japancore bands like HappyGinzaPoo and Shoko Ono, said Pat Kwiatkowski, owner of Crush Records, a local record store specializing in used LPs and hard-to-find imports. Their recent feature on KyotoFunFuns tour of New Zealand was outstanding. Paul Scobee, manager of the Stop-N-Pop, also stood by the fanzine. A few months ago, this kid asked me if he could leave a few copies of his magazine thing by the door, Scobee said. I told him yeah, as long as they dont block the entrance. So far, its been okay. The fanzines most recent error has not surprised grammar experts, who say it ranks among the most frequently made mistakes. A lot of people confuse your and youre, The New York Times William Safire said. If you are unsure, I recommend you actually spell out you are, and then see if it makes sense in context.
