I am too stubborn for my own good sometimes, but in this instance its paid off.  I did not want to wait and ask some body to help me, I wanted to find the anwer myself.  I have been looking on the internet and decided that Youtube has videos for everything, so there is probably a Diigo video on there.  There is - alot!
I have saved my first bit of information on my Diigo account and Im very proud.  Im still on basics, but atleast its a start.  I downloaded the Diigo toolbar and that made it very easy.  I just have to remember that I have this technonlogy now and to use it to save webpages and information instead of having a huge 'favourites' file on my computer and lots of scrap paper all over my desk.
The Youtube video I used was Diigo - Imporving how we find, save and share information. I also had a look at How to use Diigo for Education, some really great ideas in this video.
