We have a woman on here who I hope still lurks and can maybe answer your question- as she moved over and is deaf- so she may be able to help answer questions about the transition, etc.
Check with your local council as well- we have the Deaf Centre and its a good resource for so many. (I am not deaf, but I had a deaf co-worker, so I actually achieved Level 1 Certification in BSL through my council- and I hope to continue further- however, they're restructuring the programme- so I am waiting to find out more)
