I would like to learn BSL and wondered if there is one specific overall standard BSL and relevant gradings and qualifications or are there many different schools within the British signing communities.
If possible I would like to learn on-line from home to start with and have found an introductory course here

http://www.british-sign.co.uk/index.php

I'm unsure if it would be recognised grade for further training so any help or advice would be appreciated.

cheers
