Good at guitar, love music (absolutely have a passion), so decided that I want to sing too. So im not too serious therefore I dont want to pay money for a tutor etc.
Ive been looking around on youtube but it seems to be all out of order and confusing. Is there a website that is really worthful and teaches you from being a real normal guy into a good singer, or trains you?
Also just as a sneeky OMG AM I TO LATE panic question, Im 17, and wondering if I can get good enough to get into or start a band. I know people start playing around 12/13ish so I think im at a bit of a disadvantage. But im picking up the guitar quick, my step bro is 12 and we started playing at the same time, and im much better. Ive heard 17 is a good age to start singing because thats when your voice is stop changing? Anyway if you can answer that too cheers, optional.
Thanks for your input, appreciated.
Hopefully start a band soon 
Oh and I want to sing like rock/alternative bands. Just so you know the style. Im a complete noob =(
Oh and im scottish ¬_¬ not that has anything to do with it :S.
You are never too old to learn to sing. You first need to learn to sing then you can learn to develop style. Depending on how you learn better, you could get a teacher, get a book (self teaching), or learn online. I find it best to learn by book because you can go back and review. Online training can only go so far until they make you pay for more lessons. But since you prefer online, I provided you with the best free tips/lesssons I know of.
