Hello world!. I'm George Georgopoulos (yggeorgo@yahoo.com)

I was born in 23 Aug 1964 , married since 1995 and have 3 loving children ... a son and 2 twin daughters. I hold an Electrical Engineering Degree (National Technical University Of Athens). Except from computer programming, in my free time, I like to play chess games and also role-playing and strategy games.
