I've heard about the update and good news for Security Guide from Eric:-) Now one more guide I like to know, which is Virtualization Guide. This guide has got good attention from more than one Japanese translators, and I am guessing that this guide might be one of most wanted document from readers. This guide was released for F12 and F13, but it has not updated since then. There is no Virtualization Guide for F14 or F15. What is the plan for F16? noriko
