Not sure about zumzero being a sock puppet account, however that Mac65 guy most certainly is a sock puppet of some type. If not I wonder who he is? He knew Ken for sure.
Regarding AMC: Hello everyone, I finally got my wings to post. I'd like to repost what I put in the newbie forum about AMC.
I'm a long time computer professional...Hardware, Software, etc. I have a Business friend/acquaintance who recently made and offering on BitFunder and I would like to contribute to the discussion. I personally have known the proprietor of AMC for over 30 years and can testify that he is serious about his business, has operated many businesses, some very successful. He has sent me info relating to his plans to build the mining machines, including diagrams. How many people would be as open as he has been about themselves if they were not serious! Some people have questioned his authenticity because of his grand plans. That is the way he always goes about things. He thinks bigger than most people. To me that is the mark of someone who has the ability to accomplish big things. What ever the human mind can conceive of and believe, it can achieve...(Quote from Conrad Hill, Think and Grow Rich)
I received a very similar sounding PM from around that same time if I remember correctly. It was from LorenzoMoney.
