Hi all,

After discussing with the head honcho's it appears that nothing yet exists for newbee's to get into tuning other than to spend a few months at the keyboard reading up on old posts, posting new questions etc.

Therefore I intend to undertake the mamouth task of writting up a guide.

I just wanted to see if anyone else had started down the track, so I dont reinvent the wheel.

In fact if anyone is keen to help and do a chapter or two please let me know.

I have some ideas for distribution which might make it worth putting some extra effort in.

Anyway here is my first take at the chapters.
