Sorry to All for not answering
I wanted to say sorry to everybody who contacted me to talk, play or get some advice on the game, and... got no answer at all.
The point is that when I signed to this site and offered myself as a online chess coach I was still a student who was working on his thesis, but basically had plenty of free time. In very short time I got my MS and found a job, so I'm much less ready to spend time teaching chess online, and surely not for free :)
good luck to all with this fanstastic game
