My e-book "Start to Finish Guide to MOF Editing" is now available for purchase from SMS Expert's website (http://www.smsexpert.com/mof/guide.asp). This guide is a continuation and expansion of Micheal Schultz's original MOF Editing Guide and should prove indispensable for those SMS admins out there interested in making custom hardware inventory extensions. SMS Expert has graciously added in their database cleanup utility Site Sweeper as an added bonus for purchasing the book.
I should also mention that I worked with SMS Expert as their MOF Master during the writing of this book and since joining the team at Microsoft I am no longer professionally associated with them.
I hope you all enjoy it!
