The Learning Curve

Hi everyone,
A bit of back ground first, I have not played a guitar for approx 20 years and was only a complete novice even then.
I know a few basic cords, but as I am mainly a metal / hard rock fan my playing was just a few power cords
into bit of a Rhythm with no lead work.

So here I am on a second lap almost but wanting to learn and progress.
My question is this what is the best sequence of learning, I feel I need some kind of structure to follow, and guidance.
Is there any where on this site that shows a step by step guide on what order to progress ?
I have no idea of scales or cord progressions.
What should I be learning first and then moving onto so the previous learning/lesson/technique complements the next step.
I probably have not explained it as well as I could have so I hope you understand my point.
It would be nice to have a 10 step plan for example.

Step 1 = ?
Step 2 = ?
Step 3 = ?
ect ect

Thanks for any help or advice.

Hello From The New Boy

Just thought I would say hello as I have just signed up.
I am 40 years old and have not picked a guitar up for the last 20.
I am from South Wales in the UK
I was not very good then either just messing around with some power chords.
Musically I am mainly into Rock, Metal and enjoyed thrash.
I hope to make some new friends over the coming months and hopefully I will be able to string a tune together LOL

All the best
Conker
