Hey Commerade Ronbo,
good to hear from you and that you are settled in Russia.
I have included a link of the owner of the New Jersey Nets (Mikhail Dmitrievitch Prokhorov) who is worth about 17 billion. He knows metals mainly nickle. I saw him on 60 minutes and it was quite the story how he made his money and during some difficult times in Russia. I believe that was during the great social robbery of Russia in which George Soros had his fingers in and came away with a mine in which he should of not been eligible to bid on.
Hope you enjoy your 3 months in Russia.
