I am just a person who has listen about this a month ago more or less... and never before had think about this posibility.... so i am beginning from 0!! i just want some help... the idea is just to get inform to see if it is something interesting or not at all.... but thinking of it for the next year 2012, because like you said... their too many things to learn about this.... i wrote that i was thinking of going their in february to generate some interest in someone to help me learning about it... so if you can.... i would be all hears!!
