  1. Greetings from Los angeles! I'm bored to tears at work so
    I decided to check out your website on my iphone during lunch break.
    I really like the knowledge you present here and can't wait to take a look
    when I get home. I'm amazed at how fast your blog loaded on my mobile ..
    I'm not even using WIFI, just 3G .. Anyways, amazing site!

  2. Is the page vulnerable to XSS? Or by adding a XSS to page even though it's not vulnerable to XSS and opening it in the Comodo browser will execute the XSS?
    Do a few explaination..
