Odd-toed

Hi

I am in the UK, teaching in the North of London, one area I am very interested in expanding my teaching is to deaf and blind students. I would like to learn sign language anyway, I am aware that I need to do a huge amount of investigation into this, but I just wondered if anyone taught or had taught deaf and blind students who could give me some advice or anyone who knows of the kind of sign language courses I should be looking at attending?

Many thanks
