look I'm not all powerful or anything like that, I'm just saying that the guides are made to believe something? is to facilitate the work and learn a little more, first as you say we all have our time until we started this, but you only need to read, I do not like you i was making topics asking things alone and just try it I do that, then you better work hard to learn, not criticize comments and take them as offensive, well this is all well and if you like but also, as I said before, the guide is well explained for people who are on the subject I But good to do other greetings.
