I write a comment whenever I especially enjoy a article on a
site or I have something to add to the discussion. It is
a result of the passion displayed in the article I browsed.
And on this post "How to Crack Wi-Fi WPA and WPA2 and PSK passwords".
I was moved enough to drop a thought :-) I do have some questions for you if
it's allright. Could it be simply me or do some of these comments come across as if they are left by brain dead folks? :-P And, if you are writing at other sites, I'd like to keep up with you.

Could you list every one of your public sites like your Facebook page, twitter feed, or linkedin profile?
