After checking out the website, and translating various things using multiple add-ons through Mozilla's Add-On and extensions.. I believe this is one of the most informative reading technological news and software I've ever found foreign to my common english language. Beyond all else, I clicked most of the advertisements to insure the website does not lead to bad ads, where they install malicious malware or spam, etc so on so forth. However, I found one of the advertisements in the yellow, a cautionary tale more so. When I went into the site, and decided to play around with it a bit, it asked me to install a toolbar, which was a Green, so it's all good.. Just hassle-ing installs that has nothing to do with the advertisement site. Again; The site itself, is a 5/5 for safety, it's advertisers, I say 3/5 or 4/5, so not bad as well. Enjoy~ And Happy holidays~! -ATG-Alexander
