no problem man
we should never learn alone...ive been reading as much as i can and learning as much as possible before i ride! you can never learn too much.
just be careful with the back brake...it can help a lot of times, but in times where you need to stop fast it can really mess you up if youre not careful!
one more tip...when on gravel or any type of loose surface use the back brake! with the reduced traction you could easily lock up the front and put the bike down. just go slow and use your feet as outriggers if need be...bikes and loose surfaces dont go well together. unless youre on a dirt bike...but thats a WHOLE 'nother ballgame!
