For those who don't have the money to afford a teacher, who are self-taught and have (or haven't) had experience on another instrument...

What is some good online material, website, etc for learning guitar techniques?

I have seen justinguitar and it is quite good, but I was wondering if there was anything else.
I don't know if this is what you mean, but I found Guitar Pro to be very helpful when it comes to learning songs. Acquire it any way you like, because since you don't have the money to afford a teacher I doubt you would like to spend £50 on a program.
I love Guitar Pro. However, what I want to know are instruction vids on HOW TO play bends, arpeggios, vibrato, etc. What fingers to use when playing certain notes. I know how to read tab and universal sheet music notation (I am a piano player) - no problem.
go to pebber browns youtube and go through all of his videos. his website has a buckets of free material too.
