I'm using FF4.0.1 (updating that as I type this) and am using MS Security Essentials. I just went back to the Wiki site. When I open the link, it goes direct to a Bear Grylls knife review. Clicking the Table of Contents and choosing Tune For Mileage, it brings up Page Is Unavailable Due To Site Maintenance. Please Visit [cut off from page margin]. CLICK HERE. The link preview in the bottom left of my screen shows the link to belong to ejexatul.co.cc. Looks like, from here, your site has been taken over. I'm still looking at the PDF and the original site to see what I can use. Thanks for the response.
