The site just isn't working for me. Most links don't work. There's not much explanation of the site's purpose even. I found a publication (through a search engine). The page says "DOWNLOAD," but there's no link to download. There's a "Read more..." link, which I assumed would go to a page with the download link, or a page with pricing, or something, but the link doesn't work--the page stays the same. It may or may not be a safe site, but it's not working for me. The "Contact Us" page opens showing links, but none of the links work. The Home page has a link to "Publish Now," but it doesn't work. Other links, "Get Started Now," "Browse the Latest Publications," either don't work or only go back to the main page where links don't work. It allows me to type something in the Search box, but it won't search.
